Conscious AI as a Feature, Not a Bug


I really like the SF show Humans and its depiction of an alternate present-day UK where in addition to iPhones and super-fast internet service, humanoid “synths” have come into widespread use as servants, workers, caretakers, and companions. The basic premise is that while these robots are sufficiently human-like to engage in conversation and even sex (complete with body warmth and fluids, apparently), they are “just machines,” and people are not supposed to consider them as “persons,” though many certainly develop relationships with them, as humans do even with dogs and cats. And as with pets (and people), some humans will abuse their synths.

The big plot driver in this show (spoiler alert!) is that some of the synths have secretly been “upgraded” to possess consciousness and emotions, and when some far-fetched circumstances lead to this upgrade being pushed over the network to all synths, we have the makings of an uprising. That’s where they leave us hanging at the end of season 2, with thousands of synths “waking up” and abandoning their dreary posts as gardeners or whatever. There's a lot to swallow to really enjoy this show, but the writing and characters are good, and they manage to earn my suspension of disbelief most of the time. I'm looking forward to season 3 (I hope it's renewed). 

What always bothered me about the show is that despite their stilted speech and claims to not understand many “human things,” normal synths function at such a high level that it’s hard to imagine that they are not self-aware above and beyond whatever technical self-diagnostic systems they may have (so they can know when to recharge their batteries and recognize when another synth is not broadcasting as they apparently are supposed to do). Their ability to converse smoothly, navigate messy home and family environments, to even read human emotional states and anticipate needs, and to explain why they do things (when asked)… these suggest they are much more than “mere machines.” But would this mean they are “conscious?” What does that even mean?

This Nautilus article by a Japanese neuroscientist and AI researcher delves into this: “We Need Conscious Robots: How introspection and imagination make robots better” by Ryota Kanai.  He emphasizes that something like consciousness or at least self-awareness will be needed to allow AI systems to explain their “reasoning,” decisions, and actions to people, so people can feel more confident in and safer with these entities. But he suggests a more immediate need for such awareness – to allow for simple and common delays in their interactions with people and objects caused by distractions or other factors. Sometimes I forget why I walked down to the basement or that I put my coffee cup in the microwave, but most of the time, I “know what I’m doing” at least over a brief time period. This seemingly simple knowledge is connected to consciousness. As Kanai writes:
In fact, even our sensation of the present moment is a construct of the conscious mind. We see evidence for this in various experiments and case studies. Patients with agnosia who have damage to object-recognition parts of the visual cortex can’t name an object they see, but can grab it. If given an envelope, they know to orient their hand to insert it through a mail slot. But patients cannot perform the reaching task if experimenters introduce a time delay between showing the object and cuing the test subject to reach for it. Evidently, consciousness is related not to sophisticated information processing per se; as long as a stimulus immediately triggers an action, we don’t need consciousness. It comes into play when we need to maintain sensory information over a few seconds.
 He also talks about the need for some level of “desire” or curiosity in robots or other AI systems to avoid humans needing to spell out every detail of the simplest request. One aspect of this is “counterfactual information generation” (i.e., thinking about or modeling past or future situations, not only the here-and-now). Kanai writes, “We call it ‘counterfactual’ because it involves memory of the past or predictions for unexecuted future actions, as opposed to what is happening in the external world. And we call it ‘generation’ because it is not merely the processing of information, but an active process of hypothesis creation and testing.” He gives an example of one of their test AI agents learning to drive around a simulated landscape and deciding that climbing a hill would be a useful problem to solve in order to drive the most efficient route (without being taught or specifically asked to do this, as would normally be needed).

In the context of my home, this makes me think about how our aging dog Gracie would always like to go upstairs to sleep in our bedroom during the day, but we keep the gate closed at the bottom to limit her stair-climbing due to her arthritis. She will sometimes push open a loosely-closed door but has never tried to pull open the loosely-closed baby gate (if she learned this, we would just have to keep the gate latched). If we had a Humans-type “synth” and I wanted it to go upstairs and get me my wallet, it would have to know that if the gate or bedroom door were closed, or if something on the stairs were blocking access, it should open the gate or door or move the object. That could be some simple logic programming I suppose (if door closed, open it, unless it's locked, or something), but the more human-friendly approach would be to remember and “want to” complete the goal, independently solving any minor sub-problems along the way.

Kanai writes in conclusion: 
If we consider introspection and imagination as two of the ingredients of consciousness, perhaps even the main ones, it is inevitable that we eventually conjure up a conscious AI, because those functions are so clearly useful to any machine. We want our machines to explain how and why they do what they do. Building those machines will exercise our own imagination. It will be the ultimate test of the counterfactual power of consciousness.
This makes sense to me. If we are to interact comfortably with future robots or other AI systems, it will be helpful if they can maintain a "mental model" of our household, workplace, or other relevant environments, not so they can feel good or bad about themselves, or fall in love or whatever, but because these are things we unconsciously expect in social interactions. Simpler systems or apps, even voice-driven ones like Siri and Amazon's Alexa, can get by with being strictly transactional, to tell me the weather or play me some Talking Heads music as soon as I ask. But conversation and predictability will be a lot smoother if these systems have at least some level of self- and other-awareness and some ability to learn how things work around here. We can decide later whether this is the same as what we call "consciousness," but it is certainly like it in some ways. As AI systems improve, they will behave more and more like conscious entities, whether they are or not.

Then of course we can have that long-anticipated war between the humans and the machines. May the best entity win. But would you mind getting me my slippers first?

Nautilus is a great web-based science magazine that features essays by various writers, often touching on the societal aspects of science and technology. There's a theme for each month's issue to which the essays are at least loosely tied. This month it's consciousness.

Nothing Is Unbelievable Now

The word “unbelievable” is obsolete now that Trump is president. Any horrible thing you can imagine someone in government doing or saying is believable now. Trump's appointments and actions seem calculated to hurt the most people possible, especially if they are brown, female, or immigrants. Some of this is ideological but most of it seems more like mean-spirited bullying, a Trump specialty. It doesn't seem that these actions actually HELP anyone, not even Trump's misguided yet hopeful supporters, but he's fulfilling his wild campaign promises, so his fans are like, “hell yeah!” Many of Trump's actions will end up hurting his supporters much more than they will educated know-it-all liberals like me.

But to see this requires accepting facts and sometimes complicated reasoning. Take for example building a wall with Mexico and (maybe) imposing 20% import tariffs on goods from Mexico to “force them to pay for it.” This will raise prices on many goods for Americans (including vegetables and fruits) and probably cost jobs in industries that rely on imported parts. We could have a trade war. Americans will pay for the wall through higher prices and job losses. It will also damage the Mexican economy which will likely increase illegal immigration regardless of any wall.

As was the case during the campaign, there's such a flurry of batshit-crazy "alternative facts" coming out of Trump and his cronies that it's hard to keep it all in focus. And it's only been one week! This is all bad, but it's just the tip of the iceberg because he is also saying and doing scary things in the international arena, like saying again that we "should have kept the oil" in Iraq, and maybe we will get another chance. Statements like this are lighting up social media in the Arab world and putting at even greater risk the thousands of military personnel we still have in place helping our Iraqi allies to fight ISIS. And as Trump has been so fond of saying about others, there is clearly "something going on" with Russia to explain why he has criticized everyone from the US intelligence community to John Lewis to Meryl Streep -- but never Vladimir Putin.

Here are a few other examples just from today's NY Times.

Gail Collins suggests that Trump actually has no strong views on abortion and women's rights (or perhaps on anything but himself) but that he's just following Pence's toxic anti-woman agenda on this. He's a puppet for both Putin and Pence.

http://www.nytimes.com/2017/01/26/opinion/mike-pence-pulls-president-trumps-strings.html

Nicholas Kristoff points out that the stupid lies about inauguration crowd sizes and nonexistent electoral fraud are acting as a smokescreen for real damage caused by early actions like the abortion “gag rule” that blocks US foreign aid to any care-providing organization that even discusses abortion. This goes farther than gag rules from earlier presidents in that it will apply to all health services, including for example efforts to combat the Zika virus. Direct US funding of abortions is already banned, but this expanded policy will kill poor women in places like Africa and lead to more abortions. But Pence and Trump won't see or care.

http://www.nytimes.com/2017/01/26/opinion/president-trumps-war-on-women-begins.html

Charles Blow focuses on Trump's use of lies and criticism of the press to try to control all narratives, supplying “alternate facts” when the truth is too inconvenient, as it usually is. In addition to this, the Trump team is blocking US government agencies that deal with science from using social media and removing references to climate change from government websites. Charles Blow writes in part:

[Trump] is in fact having a running war with the truth itself.

Donald Trump is a proven liar. He lies often and effortlessly. He lies about the profound and the trivial. He lies to avoid guilt and invite glory. He lies when his pride is injured and when his pomposity is challenged.

Indeed, one of the greatest threats Trump poses is that he corrupts and corrodes the absoluteness of truth, facts and science.

Fermi Paradox Explained?


I’ve often thought that the whole “where are they?” question about SETI (i.e., the Fermi Paradox) is bogus, both because the universe is just so BIG, and because we still understand so little about it, even though we have learned in recent years that planets and even “Earth-like” planets seem to be quite common throughout the Galaxy. As smart as some of us may be, it seems likely that we are still as clueless about major chunks of physics as scientists in the 1800’s were about quantum mechanics and the scale of the universe. If there are wormholes or quantum foam or gravitational technologies we won't develop for another 200 years, there could be aliens popping in and out all the time, and we wouldn't even know what to look for. It would be like an airliner passing 37,000 feet above some remote tribe of people who have never encountered other humans or modern technology, as unlikely as that may be today.

Such advanced beings might find radio wave communication to be as quaint as rubbing sticks together as an energy technology. I’ve also read articles suggesting that we ourselves are probably approaching the end of our “radio age” due to fiber optics and other technologies. Though we still send out a lot of radio waves, they tend to be more directional (like radar, microwaves, etc.) or short range (cell phone towers, Wifi, Bluetooth, etc.). Maybe technical civilizations only use radio waves for a few years and any continued or specialized use eventually becomes very efficient with very little leakage to space.

Somehow I wandered over to Centauri Dreams, a blog that periodically blows my mind with advanced space exploration ideas. I found an article “CitizenSETI” about a couple of guys (Roger Guay and Scott Guerin) who decided to work out this Fermi thing. A key part is the lifetime of an IC (intelligent civilization), which really means the DETECTABLE lifetime. If that is very short (e.g., humans have been broadcasting for about 110 years and listening for only about 60 years), and if such civilizations are widely separated in time and space, you will have a big “synchronicity” problem – finding times and places where someone is broadcasting AND someone in range is listening.

Roger Guay created a simulation with LiveCode, a modernized version of my old, beloved HyperCard for the Mac (screen shot above). In his Advanced Civilization Detection (ACD) program, he can set various assumptions about the spacing, lifetime, and other factors and run this simulation at high speed. Under most reasonable assumptions it creates a sort of “firefly” effect with detectable IC’s flashing in and out of existence and only rarely being seen by other IC’s. If these assumptions and simulations are reasonable, IC’s could be plentiful and it might still take hundreds of years of observation to catch one of these “fireflies” before it flickers out.

I've been interested in this subject since I read Intelligent Life inthe Universe by Carl Sagan and Iosif Shlovsky back in 1974. This was a pretty early work on exobiology (or perhaps astrobiology), a field that still lacks data but provides an interesting framework for thinking about everything we know about ourselves. My guess is that unicellular life has probably evolved in many places but that the leaps to multicellular, intelligent, and technological stages are much rarer, though certainly possible (current sample size is N=1 if you give humanity the benefit of the doubt as an IC).

Based on this simulation work, we are not likely to expand that sample size anytime soon. Here is Roger Guay’s final paragraph on Centauri Dreams:

Conclusions? The ACD simulation dramatically demonstrates that there is indeed a synchronicity problem that automatically arises when ICs attempt to detect one another. And for reasonable (based on Earth’s specifications) Drake equation parameter selections, detection potentials are shown to be typically hundreds of years apart. In other words, we can expect to search for a few hundred years before finding another IC in our section of the galaxy. When you consider Occam’s razor, is not this synchronicity problem the most logical resolution to the Fermi Paradox?



Of course this is hardly the last word on the subject of the Fermi Paradox. In fact, while reading the blog posts that triggered this one, I discovered a recently updated book that goes into much greater depth, If the Universe IsTeeming with Aliens … WHERE IS EVERYBODY?: Seventy-Five Solutions to the Fermi Paradox and the Problem of Extraterrestrial Life (2015) by Stephen Webb. I've read the Kindle sample and I may have to buy it despite my insane backlog of books already waiting to be read. Author Stephen Webb also has an interesting blog

Obama Farewell


I watched President Obama’s farewell speech last night with my wife. It was an incredibly hopeful and moving speech, and the part near the end when he spoke to and about his family and his VP and friend Joe Biden was hard to see without crying. The presidency is huge, an unimaginably high-pressure job in which you are pulled in a million different directions and challenged every day to keep thousands of balls in the air. Obama did it with grace and often made it look easy, which it was not. I truly believe he is one of the most decent human beings ever to hold this office and that when he had to comfort the families of children murdered in Newtown or order military operations or drone strikes that took lives, often including innocent lives, that this responsibility truly weighed on him. I don’t want to contrast him with what is following him in just over a week. There’s no comparison. But at least we had this great and decent man as our president for eight years.

This is not to say he was perfect in office – he would be the first to say he was far from perfect. He made mistakes, some of them very costly, but very few people are in the position to judge the trade offs a president is forced to make to keep our country mostly safe and mostly free most of the time. And I far prefer the coolness of Obama to the impetuousness of… certain others.

For those of us who believe in facts, who believe in the Constitution, who believe in science, who believe that all people deserve a chance, who believe that America is a great country but not the most important one in the world – wow, he was our president. For those who hate him for whatever reason, whether it’s because they didn’t prosper while much of the country was getting better after the near-disasters of the Bush years, or just because they choose to believe that this country is somehow intended to be Christian and White, I feel sorry for them. They missed out on something great.

His speech suggested that we need to keep working for what is right even in the face of the evil that has wormed its way into Washington and will be in charge for at least four years (assuming we make it that long). He says he’s optimistic, and I want to believe him, I want to try, but it’s very hard, even for a natural rational optimist like me. I’m giving money. Can I do more than that? Can I be an activist? Can I stomach the noise of politics more than a few months every four years? I don’t know. I'm glad I volunteered for the small amount of campaign work and donated the money I did in 2008 and 2012 (and 2016), but now I can barely stand to watch MSNBC for more than a few minutes. My wife watches it a lot and she’s anxious about the coming time. I get that, wanting to be informed but scared to death of what you see happening. I'm fortunate that I am able put it aside and focus on other things – sometimes anyway.

I don’t know what to do. Reach out to the other side? Try to cross that shaky bridge? I'm not sure I can, and that in itself is a bad sign. I need to think more about it once the dust has settled a bit. But I know I will miss having a president who is smart and who I can trust to lead our country for the benefit of its people. That is a huge and scary loss.

Orbiter: 2016 vs. 2010


As I wrote recently in this blog and in an article in The Space Review, Orbiter 2016 was released in September. This is the first major release of this freeware space flight simulator since Orbiter 2010, and as I mentioned, not all of the many third-party addons for the 2010 version are working in Orbiter 2016. If you are familiar with Orbiter, you know that it's quite easy to have multiple installations of the software on the same PC, so there is no need to replace the 2010 version with the 2016 version -- as long as you have the disk space, you can keep multiple copies of both versions installed in separate folders and just run the one that has the features and addons of interest at the moment. In the picture pairs below, the top screenshot is from Orbiter 2010, the bottom one is from Orbiter 2016. 

You should also know that although there are some user interface changes in the 2016 version, they are really quite minor, so even if you are new to Orbiter, you can install and use both the 2010 and 2016 versions quite easily. Some developers have already updated their addons for 2016, and others no doubt will when they have the time and inclination. But Orbiter 2010 is still readily available, so if you are interested in the Apollo program, the advanced Shuttle Fleet, the fictional spacecraft of 2001: A Space Odyssey (sample screenshot at the top of this post) or Colliers Magazine, and many other addons, there's no need to wait for 2016 versions to come along. Note that the final version of Orbiter 2010 is often called 2010-P1 (patch-1) or 100830 (August 30, 2010).


Here are some observations and tips for working with both Orbiter 2010 and the new Orbiter 2016:

1. The biggest user interface difference is that the "no-cockpit" full screen pilot view has a control bar that appears when you hover the mouse near top edge in the 2016 version. In the 2010 version, the F4 key will pop up a small menu bar with same controls (in the 2016 version, F4 will toggle the top edge menu between "on" and "auto-hide"). See "no-cockpit" comparison screenshots above. 



2. The biggest visible difference in the 2016 is in its support for highly detailed surface terrain data complete with elevations, so mountains and craters are true 3D objects. This makes for some incredible eye-candy especially when you are flying low over the terrain, but in most situations in Orbiter, you are orbiting (oddly enough) 200 km or more from the surface, and the flat 2010 terrain textures look just fine. 

3. In addition to the general high-res 3D surface data for all of Earth, the Moon, Mars, and some other bodies, Kennedy Space Center (cockpit view above) and the Edwards AFB/Mojave region (see shuttle final approach screenshot below) have been given super-detailed makeovers in Orbiter 2016. Again, this doesn't matter much if you are in orbit or cruising to the Moon or Mars, but it does add a lot to the realism before you launch or when you are landing at Edwards AFB. 


4. There is a thread on the Orbiter Forum that reports addons that are known to work in Orbiter 2016. There are quite a few and there are probably many others that have not been tested but may work. Orbiter Sound 4.0 works with Orbiter 2016 though there are a few minor glitches such as incorrect audio feedback for some actions (e.g., the G key for "landing gear" in the Deltaglider will deploy the gear but audio will say "radiator deployed"). 

5. Some popular addons that currently seem to work only in Orbiter 2010 include AMSO (Apollo program in great detail), Shuttle Fleet V4.8 (which is freaking amazing), and the excellent "World of 2001" and "World of Colliers" addons by "Sputnik." Note that even for 2010, some addons may only work with Orbiter's "native" graphics (not the D3D9 Orbiter_NG client which offers better graphics quality and frame rate). I'm not sure how to know this for sure, but if you find that your spacecraft are invisible in the D3D9 client, you should try the native graphics version. 


6. One addon I especially like is the videnie module for orbital path drawing by "artlav." It renders orbital paths for spacecraft, planets, and other bodies in exterior views (green, red, and purple lines around Earth in screenshot above from Orbiter 2010). This is super cool and very helpful in understanding orbital paths, but it only works in native graphics mode (not orbiter_ng) with Orbiter 2010.

7. If you have plenty of hard drive space available, a good general tip is to create two separate "clean" installation folders, one for Orbiter 2010-P1 and one for Orbiter 2016, including whatever terrain data you prefer, and perhaps with Orbiter Sound 4.0 installed. Make a copy of the clean installations and install any desired addons there. Note that Orbiter 2016 installations with full terrain data can be very large (I have one installation that is 58 GB). 

8. Orbiter Sound supports mp3 playback with control over when the music plays (e.g., exterior views only). But since modern versions of Windows support multi-source sound multiplexing, I tend to just stream music from Amazon or iTunes while running Orbiter. An album of Strauss waltzes is a particular favorite, especially with the World of 2001 addon.

Orbiter 2016 Is Here


Orbiter 2016 is the latest version of a space flight simulator I have been playing with on and off since 2005. And while I'm now old enough to be a grandfather, I find that Orbiter still brings out the "space kid" in me. The sixties were a great time to be a space- and aviation-obsessed kid, and I was a NASA fan from Mercury to Gemini to the Apollo moon flights and beyond. Aside from TV coverage, my only space resources back then were books from the library, plastic model kits, LIFE Magazine, and a huge trove of "NASA Facts" and other free publications I would write to Washington to request. Fortunately NASA had a pretty big public relations budget in the sixties and they were happy to send bulging envelopes of space info to a kid in upstate New York.


I never really lost my fascination with space and aviation, as I have often discussed in this blog (though not so much recently). Thanks to personal computers and the internet, there are now more space and aviation resources than ever. I spent a lot of time in the nineties playing with various flight simulators, and I got my real pilot's license in 2001, though I ended up not flying nearly as much as I had hoped, and I am not an active pilot now. Orbiter was a great find in 2005, because it allowed me to combine my interest and experience with flight simulators with my long dormant goal of being an astronaut, albeit only a virtual one. And Orbiter was free (it still is).

Orbiter even inspired me to write a book called Go Play In Space (free Orbiter tutorial ebook), and to volunteer as a NASA/JPL Solar System Ambassador to do some space and astronomy-related educational outreach programs, often using Orbiter in my presentations as a dynamic extension of PowerPoint slides and words. The years 2005 to 2010 were probably my "golden age" for space related study, play, conferences, and educational outreach, but shortly after the release of Orbiter 2010, my company was acquired, and my professional workload greatly increased. Side interests like Orbiter largely fell by the wayside.


Things are still busy at work, but I do again find time to pursue hobbies like music and space, and with the recent release of Orbiter 2016, I'm getting fired up again. The biggest visible change in the 2016 version is built-in support for detailed 3D terrain on planetary surfaces, with gigabytes of data available for the Earth, Moon, Mars, and some smaller bodies. This doesn't matter much visually from a 300 km orbit, but when you are down low, it makes a huge difference, especially for the Moon and Mars. Earth terrain is nice too -- though not as detailed as in Microsoft Flight Simulator, it covers the entire globe (clouds are modeled too). Orbiter is primarily a space flight simulator, and although atmospheric flight is modeled reasonably well, if you are mainly interested in flying airplanes and understanding realistic flight operations, a dedicated flight sim like MSFS or X-Plane is probably a better bet.

Orbiter 2016 includes some other updates, and thanks to user interface improvements and a wide range of community-produced video and other tutorial materials, it is easier to learn and use than earlier versions, though the learning curve is still pretty steep.


I will be writing more about Orbiter 2016 in the coming weeks. In the meantime, here are some possibly helpful links, including a collection of Orbiter 2016 screen shots I have placed on my Flickr site.

100 Days


One of the most encouraging things I looked at in the NY Times this morning was the interactive "Who Will Be President?" feature, part of their numbers-oriented Upshot section. It says that based on current polling, as of yesterday, Hillary Clinton has about a 69% chance of winning the presidency. With Donald Trump continuing to double down on his crazy statements and his traitorous flirting with Putin, I have to believe that Clinton's odds will improve over the next 100 days. There will be debates (that will certainly be bizarre) and probably more surprises from Russian hackers, but I'm hopeful that Hillary's team is ready for all of this and that the Dems' convention bounce will exceed the one Trump got from the RNC. I think the DNC did a masterful job of making the case for optimism about the country and for the qualifications of Mrs. Clinton.

Of course there are always ways to look on the dark side. I also read an essay in The Atlantic summarizing the typical Trump supporter's view of "what is really going on" and why they believe he will win. It seems to hinge on voter turnout and male support. Supporters believe there are many people, especially men, who normally wouldn't even vote but who secretly support Trump and who will turn out in droves to vote for him. They believe this latent "surge" of disgruntled people is invisible in polls. Why? I'm not sure. Maybe these closet Trump supporters are embarrassed and lie to pollsters but will choose him in the privacy of the voting booth? Some of these Trumpsters even believe that many black and Latino males will go for Trump because they would feel emasculated by a woman president -- the machismo vote?

This reminds me of similar ideas in 2008 and 2012 about President Obama. It was called the Bradley Effect. It posed the idea of what you might call "embarrassed racists," people who would tell pollsters they supported Obama but who would actually refuse to vote for a black man for president. Subsequent analysis found that this did not occur -- the polls were pretty reliable. But could it be different with secret Trump supporters? I hope not.

In any case, I am excited that Hillary Clinton is the nominee and I plan to do whatever I can to support her against the very real threat of Trumpism. I can see more donations and some New Hampshire front doors in my future -- at least in the next 100 days.

Perspective


My heart goes out to the many people who have been injured or lost loved ones in terrorist actions around the world, most recently the horrific Bastille Day truck attack in Nice, France. These actions are unconscionable and the people who perpetrate or support such acts must be brought to justice.  Terrorism is obviously intended to terrorize, and these attacks are certainly scary, with the scariness amplified by instant and repetitive news coverage that makes Nice or Paris seem as close as Orlando or Boston (and for my friends in France, recent attacks have been all too close). It is a small world thanks to global communication and the internet, and we know that terrorism, like other types of crime, can happen anywhere, so we shouldn’t be complacent. But we shouldn’t panic either.

Terrorism is a real problem, but it is not the end of the world, which is currently home to some 7.2 billion humans and countless other species. For perspective, note that in the US, something like 100 people die in car accidents each day. Worldwide, over a million people die annually in car accidents, and there are over half a million “intentional homicides” each year. So many lives tragically cut short every day, yet we hear nothing about most of these millions of deaths. Commercial plane crashes are rare, and when one does occur, many people may die, so it’s big news. The same with terrorist attacks, which have become more common worldwide, though nations like Iraq, Afghanistan, and Nigeria continue to bear the brunt of those attacks, even though attacks in Western countries get much more news coverage.  

You can Google for statistics as well as I can and find that you are more likely to be killed by falling furniture than by terrorism. My wife has recently told me she’s getting more concerned about my business travel, especially to Europe. But I am far safer on a business trip to anywhere in Europe, Japan, or Korea than I am driving my car to work. I’m not saying we shouldn’t be concerned about terrorism. It’s an awful thing if this is the “new normal,” and we shouldn’t simply accept that. We can and should come together worldwide to make progress against this threat, though it is certainly not the greatest threat to civilization that we face (that would be climate change).

Steven Pinker and others have pointed to extensive data to show that even as terrorism and crime fill the headlines, the world is not falling apart, and on an overall basis, violence in the world has greatly decreased, and not only because there are fewer wars.  Other forms of violence and cruelty are also greatly in decline, though they have not reached zero and probably never will. I’m optimistic that we can still build a better world for my grandchildren -- and for everyone else. We should not be complacent about terrorism, but we shouldn’t freak out, change our way of life, or start another war over it. 

The image above has nothing to do with it except that this is the planet we all happen to share (a screen shot from the free Orbiter space flight simulator, and one of my most popular pictures on Flickr).
