Ray Kurzweil's Slippery Futurism
wjousts writes "Well-known futurist Ray Kurzweil has made many predictions about the future in his books The Age of Intelligent Machines (1990), The Age of Spiritual Machines (1999) and The Singularity is Near (2005), but how well have his predictions held up now that we live 'in the future'? IEEE Spectrum has a piece questioning the Kurzweil's (self proclaimed) accuracy. Quoting: 'Therein lie the frustrations of Kurzweil's brand of tech punditry. On close examination, his clearest and most successful predictions often lack originality or profundity. And most of his predictions come with so many loopholes that they border on the unfalsifiable. Yet he continues to be taken seriously enough as an oracle of technology to command very impressive speaker fees at pricey conferences, to author best-selling books, and to have cofounded Singularity University, where executives and others are paying quite handsomely to learn how to plan for the not-too-distant day when those disappearing computers will make humans both obsolete and immortal.'"
Seems like a lucrative field. I bet I could do it! Let me think, ah, in the future... Nope. I got nothin'.

The point isn't to be accurate; it's to be engaging. We live in an age in which it is more important to entertain than to inform. Look at all the hack prognosticators in the business and technology press who make a living making predictions – most of them are wildly off the mark but nobody cares enough to go back and call them on their failures.

I used to disdain all these vague futurists. in many cases, it's sure to happen in the far distant future, and after the fact a few act smart enough to have said it long before. And many times it doesn't happen close to the way that's predicted. I always tended toward the practical side of things, rather than the theoretical.
But one thing after another after another that was obvious and predictable just by applying Moore's law, still surprised almost everyone when they became reality. Things like lots of movies on a tiny chip.
I was a singlularity denier, for one thing. But I have to reverse myself and admit that I'm wrong. Oddly, it was Ray, presenting to an audience in Vienna, which convinced me otherwise. The only thing about being a singularity futurist is that you've predicted what's already happened. Try living without today's technology and internet and see how far you get. It's already unclear to what extent the creators (ourselves) or that which we have created (technology) is the master. We always thought that we could turn off unfriendly robots, but we can't really turn off the internet, which is the largest robot yet (and the one that replaces most human brains for getting the best answers to things).
Ray takes a lot of flak but he deserves respect, even when you think he's wrong.
OK a new size TV
We have discussed this many times. I debated writing out a lengthy post espousing the many problems with Kurzweil's predictions. Of course I (and Slashdot stories) have done this before. But you know after reading this article, I have this sort of urge to read more of Kurzweil's writings in an attempt to develop an equivalent process for identifying something we could call "Technological Stock Spiel." To some of you Sagan nuts and skeptics, you might recognize the phrase "stock spiel" as something used to designate parlor tricks and underhanded wording to get people to believe that you're a psychic. It's also been called cold reading strategy and you've seen shows from Family Guy to South Park parody it.
Basically I suspect that Kurzweil is adept at standing up in front of a group of people and employing this same sort of strategy that preys on people's understanding of technology instead of their emotions. But both of those things have in common the fact that people want to believe great things. If he's talking to computer scientists, he'll extrapolate on biology. If he's talking to biologists he'll extrapolate on computer science and so on and so forth. And he probably knows exactly what to say so that more than enough people gobble that up. Because of the things that I have studied extensively through college, this man is very capable of talking like he knows just enough and using vague analogies to get people going "Yup, yeah, uh huh I see now, I want to believe!"
As Walter Sobchak might say, "Forget it, Donny, you're out of your element!"
That is, of course, unless he's talking to a group of futurists. Then he's just preaching to the overly optimistic choir.
My work here is dung.
Why isn't there an equal skepticism about Space Nuttery like Moon colonies, space-based solar power and asteroid mining? They are equally delusional.
No they're not, and there was plenty of skepticism about such claims when O'Neill in the 70s was proclaiming that we could be doing them all in a few years, because it was clearly technologically impossible with any reasonably justifiable amount of money. There's far less skepticism today because we can see that they could be viable in a few decades.
Similarly, I haven't seen too much wrong with Kurzweil's claims, other than that he expects things to happen within the next few years, rather than the next few decades (or centuries if you're pessimistic).
I believe Clarke once said something along the lines that near-term predictions were always optimistic and far-future predictions pessimistic, because humans expect linear progress when most things are exponential.
Ironically, they will probably be saying this even if they live on the Mars colony.
A) it is assuming that we will always have a technological breakthrough at the right moment to allow the doubling of computing power every 18 months. Maybe this is the case, but it's still a big assumption.
Intel and AMD are both doubling the width of their SIMD capabilities with AVX in the next year. This is simply a design decision, not a breakthrough. More cores is also a design decision, not a breakthrough.
When the first vector processors hit super-computing, it became plainly obvious that computational capacity could always be doubled.
Remember that capacity is not velocity, or in more geeky terms.. MIPS is not MHz.. bandwidth is not latency...
There hasnt been a breakthrough in many years now, yet computational capacity continues to grow exponentially.

Greetings, my friend. We are all interested in the future, for that is where you and I are going to spend the rest of our lives. And remember my friend, future events such as these will affect you in the future. You are interested in the unknown... the mysterious. The unexplainable. That is why you are here. And now, for the first time, we are bringing to you, the full story of what happened on that fateful day. We are bringing you all the evidence, based only on the secret testimony, of the miserable souls, who survived this terrifying ordeal. The incidents, the places. My friend, we cannot keep this a secret any longer. Let us punish the guilty. Let us reward the innocent. My friend, can your heart stand the shocking facts of grave robbers from outer space?

I'm all for criticizing the excesses of Kurzweil, but I don't think the article is up to snuff and reads like a personal attack on Kurzweil rather than a well-reasoned refutation of Kurzweil's predictions.The author seems to take the position that Kurzweil wasn't exactly 100% accurate in all the factes of his predictions, therefore he was wrong and besides, somebody else already thought of it anyway before Kurzweil did. It's kind of a specious hit piece that cherry picks a couple of examples and doesn't really measure up as a serious analysis of Kurzweil's record. Maybe it would be nice of someone actually did that, but this article is nowhere near it.
How about a moderation of -1 pedantic.
Futurists don't "predict the future". They discuss the past and present, talk about its implications, and get people in the present to think about the implications of what they do. They talk about possible futures. Which of course changes what actually happens in the future. They typically talk about a future beyond the timeframe that's also in the future but in which their audience can actually do something. Effectively they're just leading a brainstorming session about the present.
This practice is much like science fiction (at least, the vast majority, which is set in "the future" when it's written), which doesn't really talk about the future, but rather about the present. You can see from nearly all past science fiction that it was "wrong" about its future, now that we're living in it, though with some notable exceptions. In fact "futurists" are so little different from "science fiction writers" that they are really just two different names for the same practice for two different audiences. Futurism is also not necessarily delivered in writing (eg. lectures), and is usually consumed by business or government audiences. Those audiences pay for a product they don't want to consider "fiction", but it's only the style that makes it "nonfiction".
This practice is valuable beyond entertainment. Because there is very little thinking by government, business, or even just anyone about the consequences of their work and developments beyond the next financial quarter. Just thinking about the future at all, especially in terms that aren't the driest and narrowest statistical projections, or beyond their own specific careers, is extremely rare among people. If we did it a lot more we'd be better at it. But we don't, so "inaccurate" is a lot more valuable than "totally lacking". Without futurism, or its even less accurate and narrower form in science fiction, the future would take us by surprise even more. And then we'd always suffer from "future shock", even more than we do now.
If we don't learn from futurism that it's not reliable, but still valuable, then it's not the fault of futurists. It's our fault for having unreasonable expectations, and failing to see beyond them to actual value.

Our joke about Kurzweil was he was someone who didn't take his "series expansion" to enough terms.. What he does is look at emergent phenomena and notice the exponential growth curve .. (which occurs in a variety of phenomena from biology to physics to even economics) .. and from that draw the conclusion that everything (or particular aspects of technology really) will continue to grow exponentially ad infinitum .. to a "singularity" etc.. This is both intuitively not true and factually not true because of resource / energetic issues (however one wants to define it for your particular problem) .. The point is you can actually look at the same phenomenon that Kurzweil claims to and notice in fact actually new phenomena/technology/etc only initially look "exponential" and then for all the obvious reasons flatten out (again really only initially (but further down the time curve than the exponential growth phase)) so your curve in the end looks really like a sigmoidal function.. (given whatever metric you choose) The hard part is to figure out how quickly you'll hit the new pseudo steady state .. but its certainly absurd to assume it never happens.. which is what the absurd conclusions he draws are always based on..

How do you know? It's only 5:30. Is that you, Kurzweil?
This space up for sale.
Of course, Bob Heinlein had his characters using mobile phones in the 50's and 60's. Between Planets opened with the main character receiving a phone call while riding a horse in the back end of nowhere. Space Cadet had the main character receiving a phone call while standing in line for processing into the Patrol, while another character mentioned leaving his phone in his luggage so his mother couldn't worry at him...
Closest to the internet I can recall was Asimov's "The Last Question", which had characters connected (various input/output methods, from voice to direct neural feed) to world- (and later galaxy- and universe-) wide computer systems.

When the first vector processors hit super-computing, it became plainly obvious that computational capacity could always be doubled.
Always? We can't make much progress without a breakthrough in efficiency. My gaming PC needs a 1 kW power supply (and 11 fans). Double that and I'll trip my breaker. Double that again and it's past what's safe for home wiring. Double that again and you're past what's safe for normal commercial wiring, and you really need something special purpose (beyond 30 A @ 240V). Give it a decade without an efficiency breakthrough and we're talking "space age" SciFi computers that filled buildings (with attached atomic power station).
Any there's only so much that can be done on the efficiency front. Beyond a certain point, addional parallelism mandates additional latency, because you need physical volume for cooling and therefore separation of components, so you're really talking about adding more computers to a network, and not the power of individual computers.
We already have a network of computers that exceeds the computing power of the human brain, IMO. What makes the human brain so amazing is what it can do with ~100 W of power. That kind of efficiency gain is not a given.
