Book reviews, Part 2 of ∞ : The Rational Optimist (continued)

It’s not every day that one reads a review in which a fan of a book pillories that same book. Alas, that’s what I find myself doing here. Matt Ridley’s The Rational Optimist is a wonderful read and I can’t argue with its central thesis, to wit: when ideas are left free to interact (‘have sex’ as he colorfully puts it), they create a wonderful synergy that leads to ever-increasing rates of innovation. This thesis in turn supports his optimism that the human race’s condition is steadily increasing and can be expected to continue improving at ever-faster rates, as long as we don’t stifle innovation.

Stifling innovation is where the stickiness begins, though. Conveniently enough, everything that happens to conflict with Mr. Ridley’s worldview and political philosophy, just happens to be exactly what is worst for innovation (and, by extension, humankind). Anything that runs afoul of his philosophy, which might best be described as an admixture of libertarianism, laissez-faire economics and neo-liberal approaches and attitudes, is perforce bad for innovation and thus quite deadly, to be eradicated as quickly as possible (though apparently not before pausing briefly to subject it to scathing sarcasm and dismissive ridicule). I get the impression that his political beliefs were changed sometime in adulthood and following a period during which he held very different positions, because usually only the converted show such rabidity in their attacks.

But again, despite his flaws and flashes of anger, I think Mr. Ridley is on the right track here, and I fully support his basic theses. But that doesn’t mean I can turn a blind eye to his work’s many, many flaws and inconsistencies. They need to be addressed, not to refute but rather to strengthen his overarching argument, because it’s one I wholeheartedly support. We need more optimism in this age of doom and gloom. All this defeatism is just leading to more defeats. We need a reason to look forward to what is in fact a brighter future. I hope that by pointing out where his arguments break down, the central thesis may be more solidly supported in future by employing sounder arguments.

Most of Mr. Ridley’s problems fall into a half dozen of categories: 1) straw-man arguments; 2) deception by averages; 3) self-contradiction, arguing one way to support a point here, then arguing the opposite way to make a different point, creating contradictions along the way; 4) glaring inaccuracies and oversights; 5) conflation/guilt by association used to attack positions (e.g. ‘Hitler was evil and a vegetarian; you are a vegetarian; ergo, you are evil'); 6) blind spots (moral, political, logical) caused by the dogmatic nature of this beliefs. Covering all of these in detail would require that I write a book of my own, but I do want to flag a few of the more egregious issues.

Straw Men of the World Unite! Mr. Ridley needs you! To refresh the memory: a straw-man argument is an oft-employed tactic in rhetoric in which one creates some absurd version of one’s opponent’s position, then attacks that absurd version, without ever having to address the real, original version of the argument, then using that sleight of hand to convince the audience of the absurdity of the opponent’s position. An exaggerated example: I say to you that it’s a good idea to include apples in school lunches, and you refute this position by say something like, ‘So I guess now all our kids are going to be vegetarians! What do you have against the meat industry? Do you realize how many jobs would disappear if you put the meat industry out of business? Why are you anti-jobs, Mr. Hughey?! Stop pushing your radical job-killing agenda on this community!’

Mr. Ridley most often employs this tactic when discussing environmental regulation. He argues against many green initiatives by taking them to the most extreme possible versions, then attacking those extremes. For example, he notes that to move completely away from fossil fuels, the UK would have to take measures that indeed sound absurd (e.g. covering 10% of the land with wind farms and areas the size of Lincolnshire with solar panels). His decision to focus on the UK in isolation makes his arguments even weaker, since the UK is unusually highly densely populated AND is a high energy consumer (giving an energy usage/land area ratio of 1.25 w/sq meter). Folks like Ridley speciously use this outlier as an example of why too much energy per square meter is required to make something like biofuel possible, as it only yields .5 p/ sq meter. If UK is the outlier, why is it a valid example? Yes, if we shut off fossil fuels tomorrow (an absurd notion) and used only current technology (equally absurd given the time frames for transitioning away from fossil fuels) and chose the mix of solutions that would work only in isolation (e.g. don’t put panels on buildings, but take up land dedicated solely to the panels), then yes, that would be nutty….so clearly the entire environmental movement is absurd and can be safely dismissed! Yay fossil fuels! How silly and juvenile. These scenarios he describes remind me of the old adage about current trends: if current trends can’t be maintained, they simply won’t be. If ‘at current trends’ the mile will one day be run in ten seconds, then clearly the current trend won’t prevail! So if with current technology we would one day have to tear up all green spaces to make way for alternative energy production, clearly that will never happen! He’s also rather absurd in his assumption that land area taken up by production of renewables is land area lost to people. It’s not a zero sum game: solar panels can occupy roof tops, for example; wind farms can be put offshore; ocean wave energy plants can be put in areas not readily accessible or even necessarily desirable to people.

      His stance on alternative energy also assumes no progress will ever be made in the efficiency of these sources, so, he seems to argue, why bother with them? By similar reasoning, we should never have bothered with oil or gas, because only deep-sea drilling, advanced extraction methods and (in the case of gas) hydrofracking have yielded the volumes we’re able to achieve today. But none of these techniques existed when we first started getting fossil fuels out of the ground. Only by investing in fossils over many years did we come up with these new techniques.

Inaccuracies. Any book sufficiently dense in facts and figures will inevitably contain some innocent mistakes. To make too much hay out of innocent oversights/errors is to descend into pedantry. But there are cases in Mr. Ridley’s book where one gets the sense that the oversights are almost willful attempts to prop up arguments with convenient lapses. For example, Mr. Ridley is very dismissive of theoretical scientific research and apparently finds it quite the waste of human effort and resources. He claims that all the useful technology in the world has come from practical research carried out with profits and gain in mind. What utter nonsense and bunk. And one needn’t look outside Ridley’s own work to find examples to support that opinion: he talks about the usefulness of the laser, but that device would not have come to be without a solid theoretical basis of work done by people who had no industrial applications in mind. And the modern world Mr. Ridley loves would scarcely even be possible without the breakthroughs of Michael Farraday, a man Ridley conveniently ignores but whose whole life was dedicated to work that can pretty fairly be described as theoretical. Without his work, without his discoveries, we’d have few of the modern marvels we take for granted.

Being a Libertarian, Mr. Ridley also conflates the amorality of market mechanisms with the amorality of its players. I'm a firm believer that markets are among the most efficacious means of achieving goals, but they rarely address the negative externalities  associated with them, so leaving them entirely to their own devices means too many people often get hurt in the process. So by all means, let markets do their magic, but where they fail to address human needs, apply corrective incentives (as opposed to punishments) to encourage better outcomes. Mr. Ridley sees that as too much of an encumbrance to free markets; I say markets aren't infallible gods and we shouldn't worship them as such.

Unemployment is a perfect example of this. The way our market system is set up, there simply can't be zero unemployment. If there were, inflation would soon spiral out of control. So if this imperfection of the market system is undesirable but also necessary, may we not mitigate its impact by helping the poor and unemployed? After all, we owe our prosperity to some percentage of people unable to get work. So why not address this negative externality associated with inflation control? 

I also take issue with Mr. Ridley's view that all government is just some stone around our necks. Through government we can accomplish greatness and handle tasks the market simply won't solve, such as roads, police, education, etc. And despite his silly statement to the contrary, no, 'some rich guy' wouldn't have gone to the moon without there first being a massive public investment in NASA. That was a perfect case of the groundwork needing to be laid by the public so that the private sector could follow. 

Finally, I take issue with Mr. Ridley's anti-tax extremism as it ignores the role taxation plays in leveling the playing field. (Leave aside for the moment the fact that there is simply no evidence that cutting away taxes and regulation creates jobs.) Unfettered capitalism in low-tax environments is leading to ever-increasing gaps between rich and poor that won't just go away and that are holding us back, meaning the optimistic world Ridley inhabits simply can't be maintained if people like him get their way and the gaps keep widening between rich and poor. Mr. Ridley would counter that 'on average', we are all getting richer, but that's meaningless if that average moves up only because the top 1% are gaining much more even as the poorest lose out. If I have 100 apples and you have one apple, and I get two more apples while you lose yours, then on average our little group has gotten richer (going from an average of 50.5 to 51 apples per capita)....but under the circumstances, do you care? Mr. Ridley would say huzzah, we're all richer! I don't buy it. 


So, in conclusion, I think Mr. Ridley's overall message is a sound one and I fully support the idea that innovation is the driver of our better tomorrow. But he is too blinded by partisanship and ideology to see that there are limits to the model he describes and supports.

Great Books, Part 2 of ∞ : The Rational Optimist

The second book in my ∞-part series of book reviews, is 'The Rational Optimist' by Matt Ridley. I scarcely know where to begin, which is why this review is being started so late and likely will not be meeting your eyes until considerably later. This book is unnerving to me because I am so conflicted about it. One the one hand, I have no disagreement with Mr. Ridley on his core thesis, which boils down to the idea that progress is inevitable when ideas are allowed to propagate freely, and that progress in fact speeds up faster and faster the more ideas, as he puts it, are allowed to 'have sex'. If we don't meddle with creativity and just let the great marketplace of ideas run freely, we will reap rewards with no diminishing return, hence his giddy (yet, in theory, rational) optimism. Throw in unfettered comparative advantage and we might as well stop worrying about anything at all! Sounds great. And in fact, Mr. Ridley managed to change my way of thinking on a few subjects. But still, with so many, many problems of logic and reasoning, not to mention just plain factual errors, I can't share his unbridled enthusiasm.

So where do I begin? I am not even sure I can begin here in a blog. To be honest, the issues and problems addressed in Mr. Ridley's book have made me think there may be an entire book just in addressing it all. I have been taking notes as I read through the book and so far I have several dozen pages of comments and rather alarming issues...and still have another 100 or so pages of his book to go! (Yes, rather dilatory, but in my defense, I have in the meantime read another 12 or so books...I can never be accused of focus.)

Stay tuned.

Beam me down, Scotty.

I said recently that there are some annoying aspects to sci-fi. But when I watch old episodes of Star Trek from the 1980s/1990s, as I did this past winter as the snow hemmed us all in, what strikes me is not how outlandish some of it is, but how much they underestimate the tide of science and technology. As I said in a recent post, there are those who suggest that we are nearing a technological singularity, a point past which society will be unrecognizable to those on this side of the singularity. I said then and repeat now that I am skeptical of this idea, but there are signs that something is hurtling towards us, for good or ill.

Look at some of the 'marvels' in those old Star Trek episodes:

-I recently saw an old episode recently in which they talked about the problem of it taking months before they could sequence a genome to find the problem at the crux of the episode. In the 24th century. In 2011, it takes a few weeks and the price is in the tens of thousands of dollars. I suspect that within a few short years, it will take days and cost hundreds. I have had mine partially sequenced for USD 99!

-In one episode, set in the future even in relation to the show's timeline, a man's sight was restored by implanting cloned eyes. A few years ago, a woman in Spain had a new windpipe implanted: it was essentially her own, as it had been 'manufactured' from an old one using her own cells.* Scientists are now experimenting with growing organs on demand. Liver failing? We'll grown you a new one and get it to you next week. That's not 24th century. That's probably a few years away.**

-In another scenario, that same blind man's clunky 'visor' was replaced with mechanical eyes a few years later. This 'breakthrough of the 24th century' is already happening now, in fact. The first primitive (60-pixel) prosthetic eyes have already been developed and approved for implantation. Wearers can at least discern light and up to eight colors, and see well enough to navigate safely. And that's version 1.0. I would be surprised if we didn't have HD-quality resolution that restored most sight within another generation or so, right here in the Dark Ages of the 21st century.

-Remember the old tricorders and communicators from the original show? My iPhone can do 1000 times more than those clunky things ever could.*** I can whip out this USD 199 device and do things Captain Picard would need his ship's computer to do.

-Speaking of computers. Are you kidding me? That piece of junk on the Enterprise often did things in hours that my laptop could do in minutes or even seconds. There are already supercomputers capable of memory and speed that are comparable to those of a human brain. In ten years, we'll probably have laptops of that capacity. And how about those huge computers on the original series?! Please. We surpassed those before Shatner bought his third toupee.

-On a related note, I saw an episode in which the characters were in awe of an android that performed at 60 teraflops. I am no expert on this, but from my admittedly cursory investigation, it seems that's peanuts! Our current supercomputers are measuring in petaflops, not teraflops.

So skip the beam-up, Scotty. I am doing just fine down here.

**Well, assuming they can sort out the pesky issue with the connections: making an organ and hooking it up to the body's blood supply are two separate tasks, and it turns out the latter is harder. It's like being told that creating an HD TV from scratch is easy-peasy, but figuring out how to plug it in is superlatively difficult.

Great Books, Part I of ∞ : An Optimist's Tour of the Future

I've no experience at all with book reviews. Giving my opinion is hardly problematic, as I warned in my inaugural post. But summarizing is not my forte. If anything, I tend to do the opposite of summarizing: give me a paragraph and I will give you a book. When trying to review an entire book, then, well....I just hope blogspot doesn't charge by the word.

Nevertheless, here I am trying to do a book review. Why? Because I am suffering from an embarrassment of riches of late. I have come across so many wonderful books in the last couple of years that I am bursting to share them all. I haven't come across such a wealth of wonderful reading since I was a very young man*, back when ALL wonderful literature was new to me. So, over the coming months, I will share some of these titles and my thoughts on their content and worth.

Among the most recent is Mark Stevenson's An Optimist's Tour of the Future, an insightful and inspiring (if occasionally mildly terrifying) book about the latest trends in all the technologies and ideas that will shape the world to come. I was fortunate enough to read an advance copy of the book, which is being released in the US on 3 February 2011. After I read it, I began a correspondence with the author, who is one of the most genuinely kind people I have had the pleasure to 'e-meet', the electronic nature of our acquaintanceship notwithstanding. I mention this only in the interest of full disclosure: I am reviewing a book of a person whom I have come to know (albeit to a necessarily very limited extent). But to be clear, reading and admiring the book came first and my reflections are thus free of any bias: I would not have reached out to the author had I not already respected his work. So with all the disclosures out of the way...

Think back over the past few years and think about the books you've read on the current state of the world and/or its fast-approaching fate. Then, when you get back from the pharmacy and take your copious amounts of anti-depressants needed to cope with those books, pick up a copy of this book and throw out the pills. Amid all the doom and gloom, here's a blossom of hope. Mind you, Mr. Stevenson is no naïf in rose-colored glasses: he approaches his subjects - among them some of the world's most brilliant people - with an intelligent skepticism, challenging their assumptions and never letting them off the hook when they try to wiggle out of the tough questions.

To get a sense of Stevenson's style and approach in this book, think about the motivations behind "What Are You Optimistic About?: Today's Leading Thinkers on Why Things Are Good and Getting Better", combine it with the probing intelligence and never-say-die quest for creative answers behind "Freakonomics", then dash in the wit and wisdom of a Bill Bryson.

Each section of the book covers a specific topic, with subjects ranging from transhumanism to robotics to the environment to genetic engineering (to name but a few). But more interesting still are the people working at the cutting edge of these fields. In each section, we follow Mr. Stevenson around the world as he visits some of these leading minds of our time, visionaries like Ray Kurzweil, George Church and Vint Cerf. Through wit, charm and intelligence, he elicits a level of frankness that you will not witness in any other interview format. (In that sense, the book is worth the price for the biographical components alone.)

I think the biggest selling point of this book, though, is the way it alters the reader's whole way of looking at an exciting future that is so much closer than most of us might think. Stevenson calls it a 'reboot', and that's a very apt descriptor: the reader finishes the book with a sense of awe (and yes, some trepidation) about a future in which everything we have taken for granted for so long, is suddenly washed away in favor of very new definitions of things as fundamental as success, happiness, relationships, even mortality.

So put down the doom and gloom for a while, turn off the 24/7 parade of dismay and pick up this reason to be optimistic. The future is going to be a wild ride, and Stevenson's book is a good road map.

Yet another step towards the singularity...

A few years back, I remember reading an article about Vernor Vinge and his case for the technological singularity. I found it fascinating, but soon it crept to the back of my mind. I didn't see much evidence that it was approaching anytime soon. But recently, some breakthroughs in science and a wonderful new book by Mark Stevenson, have made me revisit the idea. In its simplest expression, it basically just says that at some point in the not-too-distant future, accelerating returns will result in a watershed moment, after which humankind will be so changed that all of our current assumptions about even the most fundamental concepts will be swept away, leaving us in a world so completely different from the one we had come to know as a species, that it will be essentially impossible to predict from this side of the singularity. So when will this point be reached? It is not too surprising that no two people agree and even less so that many people think the whole concept is bunk. But people like Ray Kurzweil seem to feel that many people alive today will live to see it. I am not sufficiently convinced even of the validity of the idea just yet, never mind having an opinion about timing. But after reading books like Mr. Stevenson's and seeing some of the mind-blowing advances happening in so many fields, it is certainly something that won't be creeping off again to the back of my mind any time soon.

To cite just one (albeit very powerful) example, consider Eureqa, a program developed by Professors M. Schmidt and H. Lipson at Cornell. Mr. Stevenson visited the team at Cornell and discusses it in his book. Basically, this AI 'program' - calling it a program seems akin to calling Mt Everest a 'mound of dirt' - takes your data and derives principles on which such data are built. That may sound rather dry and dull, but consider this: it figured out Newton's Laws of Motion based on data it was fed. In a few hours. So imagine brilliant careers in research distilled down to a few hours. Then consider that of course such minds won't retire after they feed an AI like Eureqa some great data and get some cool new fundamental laws. They will keep going. So imagine Newton figuring out his laws in a day and then going for another 40 years or so. (Well, OK, he DID keep going for another 40 years or so, but you get the point.) Starting to see how accelerating returns might be leading us somewhere unrecognizable?

If you're one of the select few scientists with access, you can feed...oh, wait, what?! Eureqa is a free download. Anyone in the world can use it. I have.* It's laid out like Excel. I'm no scientist and I doubt I will come up with any Earth-shattering theorems with Eureqa. But imagine this tool in the hands of thousands of brilliant researchers around the world.

Hold on to your hats, folks. It's gonna get wild.

*I love playing with economic data, so I fed it 30 years worth of such data to see what equations it would come up with. This was just to amuse myself, mind you: one must be careful to distinguish between deriving laws from data gotten from the natural world v just plain data-mining. My exercise was essentially the latter. In other words, any equation derived from something as erratic as economic data will serve just one purpose: more or less accurately predicting a data point within the universe of data already provided to the AI. So if I got an equation for predicting, say, the value of the S&P 500 based on CPI and consumer confidence, all I could be certain of would be that the equation could more or less accurately 'predict' the values for 1987, using the other 29 points of data within its universe. Still, it may serve to give a general sense of trends.
