I find Kerzweil to be a fascinating character. There is little question about his genius, but many of his ideas come off sounding rather "woo woo". The guy is obsessed with immortality....or at least extreme longevity. Can't say I argue...I'm all for extreme longevity...I picture aging as a disease....therefore there's a cure out there somewhere. Nanotech looks like the best bet. Of course that which can cure you can often kill you even quicker.
Will "Drexler's" nonobots become a reality?
If so, will they appear as quickly as Kerzweil predicts? (roughly 2030's)
Will human level AI become a reality?
If so, will it happen as quickly as Kerzweil predicts? (roughly 2020's)
If so, will AI that FAR SURPASSES human levels happen by 2040?
If so.....then what happens?
For me.....I hope yes. I don't see where it isn't possible. I do see where it could result in our destruction as easily as to our benefit. But that fact alone will not prevent it from happening. I don't think you can stop technological progress. You can attempt to prepare for it.
If true it's coming and coming very fast....faster than most people would be ready for. That could be a major problem.

I have heard of the concept; but I am a bit suspicious.
One of the thing is Moore's law: 'processing power doubles every two years' that is almost always quoted. First of all; it's not really a law, more like an observation. The fact that it, roughly, happened in the past is not an indication that is will necessarily happens over the next decades. Second: especially as, because we'd need smaller and smaller processors, we are going to run into problem as the quantum mechanic are becoming relevant.
Also, how do you define intelligence? Computers are already 'smarter than human' in many respects. The article touch on that, mentioning that we need 'smarter computers'. Ok... and how? The article offers no answer.
I guess, it is possible. I do not see any absolute impossibility[1] but I would not expect it so soon.
As to how and when it will happen. Well, live and learn... but that could be a really exciting time.
Also: because Kimiko is the cutest!.

Predicting the future is dicey business. Kurzweil has made some reasonbly accurate predictions in the past though.
He is, I think, on to something with his observation of the rate of increase in the speed of knowledge acumulation and technological advance. The specifics though? I dunno. AI is , as Ricky points out, a hard problem. |

Neural networks are becoming vastly more complex as the hardware gets better, but still far enough away from anything resembling intelligence.

Since Kurzweil has already answered your question I will let him do it. Outtakes from http://www.kurzweilai.net/meme/frame.html?m=4:
I still run into people who claim that artificial intelligence withered in the 1980s, an argument that is comparable to insisting that the Internet died in the dot-com bust of the early 2000s.6 The bandwidth and price-performance of Internet technologies, the number of nodes (servers), and the dollar volume of e-commerce all accelerated smoothly through the boom as well as the bust and the period since. The same has been true for AI.
A rash of AI companies occurred in the 1970s, but when profits did not materialize there was an AI "bust" in the 1980s, which has become known as the "AI winter." Many observers still think that the AI winter was the end of the story and that nothing has since come of the AI field.
Yet today many thousands of AI applications are deeply embedded in the infrastructure of every industry.We are well into the era of "narrow AI," which refers to artificial intelligence that performs a useful and specific function that once required human intelligence to perform, and does so at human levels or better.
Every aspect of understanding, modeling, and simulating the human brain is accelerating: the price-performance and temporal and spatial resolution of brain scanning, the amount of data and knowledge available about brain function, and the sophistication of the models and simulations of the brain's varied regions.
we will have detailed models and simulations of all regions of the human brain by the late 2020s. Until recently, our tools for peering into the brain did not have the spatial and temporal resolution, bandwidth, or price-performance to produce adequate data to create sufficiently detailed models. This is now changing. The emerging generation of scanning and sensing tools can analyze and detect neurons and neural components with exquisite accuracy, while operating in real time.
Future tools will provide far greater resolution and capacity. By the 2020s, we will be able to send scanning and sensing nanobots into the capillaries of the brain to scan it from inside. |

The Law of Accelerating Returns by Ray Kurzweil
An analysis of the history of technology shows that technological change is exponential, contrary to the common-sense "intuitive linear" view. So we won't experience 100 years of progress in the 21st century -- it will be more like 20,000 years of progress (at today's rate). The "returns," such as chip speed and cost-effectiveness, also increase exponentially. There's even exponential growth in the rate of exponential growth. Within a few decades, machine intelligence will surpass human intelligence, leading to The Singularity -- technological change so rapid and profound it represents a rupture in the fabric of human history. The implications include the merger of biological and nonbiological intelligence, immortal software-based humans, and ultra-high levels of intelligence that expand outward in the universe at the speed of light.
Also, how do you define intelligence? Computers are already 'smarter than human' in many respects. The article touch on that, mentioning that we need 'smarter computers'. Ok... and how? The article offers no answer.
Passing the "Turing test" is generally accepted. Of course by the time virtually everyone agrees that an A.I. has passed the test A.I. will probably have surpassed us.
I guess, it is possible. I do not see any absolute impossibility[1] but I would not expect it so soon.
I still see no glaring flaws in Kuraweil's reasoning....he may very well be wrong....but there is no pressing evidence against his theories.

Agreed...predicting the future is very dicey...most fail miserably. But I find his "Law of accelerating returns" very fascinating. So far it appears to be damn near spot on.
AI is a VERY difficult problem....possibly the last one we will need to solve (as biological humans anyway). But exponential technological growth is a freight train (if it holds). |

If you truly believe that, either I am not making my point clear enough or you are not understanding what I am saying.

That is precisely not what I said.
Yet today many thousands of AI applications are deeply embedded in the infrastructure of every industry.We are well into the era of "narrow AI," which refers to artificial intelligence that performs a useful and specific function that once required human intelligence to perform, and does so at human levels or better. |
I agree completely with Kurzweil here, and even used the same exact term. But to call this "intelligence" is misleading. A human can do single variable calculus all day long without understanding what the symbols mean. It would just be at that point symbol manipulation and nothing more. This is exactly what a computer does. But on the other hand, a human understands what a derivative means, what it represents. Calculus isn't just symbol manipulation and in that sense, computers can't do calculus.
we will have detailed models and simulations of all regions of the human brain by the late 2020s. Until recently, our tools for peering into the brain did not have the spatial and temporal resolution, bandwidth, or price-performance to produce adequate data to create sufficiently detailed models.

I find this prediction to be rather unfounded and unconvincing. There is also no evidence to suggest that even if we do have detailed models of and simulations of the brain that this will have any positive influence on the field of AI. I'm not saying that's what we shouldn't be focusing on, but there is a huge chasm between model of the brain and a working AI.
And of course there is the date discrepancy. First he predicts nanobots by 2030's and now 2020's? |
Why continue? Because we must. Because we have the call. Because it is nobler to fight for rationality without winning than to give up in the face of continued defeats. Because whatever true progress humanity makes is through the rationality of the occasional individual and because any one individual we may win for the cause may do more for humanity than a hundred thousand who hug their superstitions to their breast.

Sorry....the date discrepancy is probably mine....I was working from memory on those.
You don't think having detailed models of the brain would influence A.I.? |

Also....I'm not some fanatical Kurzweil lover. I just find his theories very compelling and have not seen a rock solid argument against them. He could be wrong....but even if he is I think it's more a matter of time (which he lays out in detail) than execution. Nanobots & AI are coming; unless we destroy ourselves first (IMHO). |

If am iffy on the law of accelerating returns myself.
I mean, for the longest time, progress was so slow that a logarithmic progression would not have been too different from a linear one. Not to mention, periods like the fall of the Roman Empire when the technological levels actually went down in most of the world.
It has mostly been for a short time (at the scale involved) that this model seems to fit better, and such a time has been too short to really extrapolate it as being a law.
The US in the last 20 years, for example, have experienced what seems like a decrease in scientific literacy of its population as well as a decrease of science standing.
I am not necessarily disagreeing, once again, just seeing that I am reserving my judgement for the moment. |

That's pretty much it, isn't it? Personally, I would consider a computer intelligent when it is capable of understanding what it is doing... and that in itself is a very abstract concept. While we are advancing towards the notion of computers that can "learn" and associate and, to some degree, understand the meaning of things, methinks it'll be more than twelve years until we get to "human" level. We are, after all, in 2008.
Possible? Most likely yes. This quick? I don't think so. |

Which, oddly(/sarcasm), has nothing to do with the observed rate of technological advance.
While the time period may be too short to infer a "law", the hypothesis seems to fit the date for this time period fairly well.
It's like Moore's "law". While it probably shouldn't properly be called a law, the observed trend fits the predicted trend...so far.
Kurzweil has a fair track record, he doesn't claim absolute certainty in his predictions, and his reasoning (within the context) is sound. He is a credible person and it is impossible to dismiss him out of hand. He predicted, in 1990, that a computer would beat the best humans at chess by 1998. Deep Blue beat Kasparov in 1997.

I am not dismissing him by any stretch. Just stating my lack of conviction either way.
Indeed, the trend I spoke of has not affected the rate of innovation but I am not sure if it will last. Already, the number of researcher and graduate students that have to be 'imported' in the US has greatly increased in the last decades. I am not confident about inferring anything about it but the trend seems real.
I am just not sure. If the war lasts 100 years, if the price of oil keeps going up, research's funding might suffer a lot. |
