Re: David Brin's latest novel, and a TED talk
No, quite honestly when I see rebuttals on websites, these are the best criticisms they can come up with! Yes, they are pretty easy to shoot down, as they have been many times before. People keep saying the time frames are wrong, but as I said, they don't take into account accelerating returns...as I posted before, 50 years for monkey level AI, far faster than human evolution, you really think the explosion of info tech won't increase the rate of AI advancement? I think it's those who claim strong AI is not possible for a 100 years or more who will be quite surprised. No good reason to believe in SIngularity transhumans within our liftetimes?? Well that's the crux of the argument isn't it! Both AI/cyberneticists posited the timeframe before those who posited most of the transhuman elements that have been popularized now. The timeframe that human level AI and world level AI fit neatly into the time period. Some, like Vernor Vinge, seems to feel the timeframe is even earlier, happening in the 2030 range. Infinite growth: in fact this is one of the most common arguments against the Singularity. I read it in almost every counter-article. The idea probably originates in the fact that runaway AI reaches a level we can't predict, which to many is judged as "infinite". I've also read the related criticism quite a bit: that exponentials end...I believe I answered that adequately in my earlier post. Computers eventually will not just do what we tell them to, they will learn, your assumption here is completely incorrect even in 2012. By definition, if they surpass human intelligence, they should have the capacities that we do, but at much greater speeds also. See the link below. There is a huge difference between just saying strong AI is around the corner, and predicting it based on mathematics of computing power and speed. It should be possible. Even naive simulation of the whole human brain would cost just $40 per hour:

Re: David Brin's latest novel, and a TED talk
If you think there are no differences from IE 2 and my current Chrome of Firefox then you really haven't been paying attention. I do realize some people want to remain firmly rooted in safe observances of past change.

Re: David Brin's latest novel, and a TED talk
Some of the machine takeover movies are good in their own right, but they are still kind of unimaginative and don't really ask any of the important questions...they only take one view of the AI reaching human levels at all. The Matrix series is probably the most complex of the machine takeover genre, as far above Terminator in the conceptual scale as can be and goes beyond the usual pedestrian cautionary tale like Roboapocalypse. The humans even debate the machine designers! There is a negotiation in the end and an uneasy peace. There are traces of Han Moravec's speculations, tons of transhumanism elements, even philosophical questions of existence.

Re: David Brin's latest novel, and a TED talk
There is no reason based in evidence to expect this to happen soon, if ever. So, what is this assumption based on? Faith. Wishful thinking. Nothing more, no observations drawn from history or the real world. Attempting to use the applicability of Moore's law to computer hardware as a starting assumption and basis for extrapolating a similar exponential growth and evolution in processes of a different sort and order exposes the essential laziness in the thinking of Kurzweil and his ilk. As others have pointed out, it's worth considering that biological evolution (the touchstone model here) has not, despite a head start of billions of years, stumbled onto the "algorithms" which would support exponentially accelerating change of this kind (despite the self-evident utility of such for the adaptation and survival of living forms). The basic presumption underlying groundless faith in the Singularity is that it will happen now because we're special and living in a special time. Also, we don't want to die. As someone said, it truly is "the Rapture for geeks."

Re: David Brin's latest novel, and a TED talk
When I was thinking about this last night, I realized the same thing you posited at the end: that it's not unlike Christian apocalypticism. On top of being a belief that we live in a "special time," it also seems to be used as a magic wand to wave away the urgency of the present world's problems. There's no reason for people to worry about climate change or the energy crisis or the exhaustion of finite resources; the Singularity will happen soon enough and all our problems will be solved. It is the height of intellectual laziness. We assume our problems will be solved in time because we've managed to get through so far. But, as they say in every Wall Street prospectus, "past performance is no guarantee of future returns." I was working on a longer post to address RAMA's specific points, but since Dennis summed it up so well, I'll just cover the part I think is the greatest weakness in the assumptions of Singularity prophets. Kurzweil's point about accelerating returns makes no sense. It's quite a leap to compare the physical laws of the universe (which do not change over time) with the outputs of human processes. He dismisses the notion that "laws work until they don't," but it happens to be true. You know what's fueled the past couple hundred years of human advancement? Fossil fuels. I'm not here to give you the Gospel of Hubbert and talk about "peak oil," but the fact remains that the industrial and technological boom we've experienced since the Industrial Revolution has come from the consumption of a finite resource that we will eventually exhaust. The EROI (energy return on investment) of fossil fuels is higher than anything else we have apart from nuclear, which has its own set of difficult problems. You cannot extrapolate accelerating, exponential growth infinitely into the future when it depends on resources that are finite and have no practical replacements. It is also not safe to assume research pressures will inevitably solve the problem. Put simply, it's not just about technological research, it's about the characteristics that fundamentally underpin the progress of human civilization--and the heart of that is energy, energy which is becoming harder and harder to obtain, and the cost of which is increasing both in financial terms and environmental impact. We've been accelerating the use of fossil fuels for 200 years, and when they're gone, they're gone--do you really think the pace of technological development and deployment will continue unabated once we hit that particular brick wall? Finally, what Dennis said about wishful thinking with regard to computers writing their own software is absolutely true. Do we have code generation today? Yes. Is it anywhere near as fanciful as guys like Kurzweil think it is? Hell no. It is nothing but a shortcut so developers can get away from writing the same tedious code over and over; it's not a magic bullet that lets computer systems write themselves. We've also been toying with genetic algorithms in computer science for over 50 years, and while they're useful in some very limited problem domains, they don't bring us anywhere near this notion of generalized AI. The assumption that simulating a human brain will result in generalized AI is also totally faulty, mainly because we so poorly understand how the interactions of neurons and chemicals results in the properties we see as intelligence and consciousness. How are you going to simulate something you don't even understand?

Re: David Brin's latest novel, and a TED talk
Somehow. The ways of animal and human behavior aren't based in intelligence per se but in the layering and idiosyncratic interaction of late-evolving systems over older "legacy" systems in a process which has developed to maintain internal homeostasis against inexorable decay and entropy.

Re: David Brin's latest novel, and a TED talk
This conception of a "Singularity" really can be extrapolated from Moore's Law etc., though I think the proponents neither mean this nor are extrapolating prudently. An expert system/intelligence that can simulate a human personality is another question, taking us right back to the difficulty of modeling something you don't understand. Analog models can do this, however. Neural networks can be interpreted as doing this algorithmically (without human understanding.) But here the Singularity advocates seem to be forgetting the distinction between a simulation and the original. Downloading minds is basically the notion that your soul can be put in a bottle. Taking umbrage at the notion of copying minds smacks of being angry at the hubris of thinking man can create a soul. If God is truly that offended, however, surely He can defend His honor Himself.

Re: David Brin's latest novel, and a TED talk
The problem with "downloading minds" isn't one of "taking umbrage" but that it's the equivalent to "bottling unobtainium" - you've got a verb acting there on a noun that stands in for something with poorly or undefined characteristics and which there's little reason to think actually exists as an entity. One doesn't download a thing, anyway - one downloads a copy of it. That a copy of me may exist after my death is of no actual interest to me, or at least not of as much appeal as the hope that my children will exist after my death.

Re: David Brin's latest novel, and a TED talk
1. They lack the ability to create novel ideas or concepts 2. They lack the ability to make intuitive leaps of logic or to make a conclusion without clearly set parameters aka they lack a "gut". They also lack emotions but it's debatable if a true AI needs them.

Re: David Brin's latest novel, and a TED talk
Also, it is still simply an error to insist that the "mind" has to be understood to be modeled. One may insist that one doesn't believe in "souls" but if they hold a concept that has supernatural powers, such as ineffability, no one else is required to take the claim seriously. (Technically, one might claim that the "mind" is a QM phenomenon, hence uncopiable. Or one might claim that the "mind" is inseparable from the activity of the body and uncopiable for about the same reasons as one could not copy a flame. But no one has made such claims, have they?) I believe RAMA et al. are wrong, but insisting they are stupid or crazy is symptomatic, not common sense.
2. Logic is not intuitive, nor does it take leaps. Conclusions can be made with fuzzy parameters, but there's no reason to want expert systems to do what people can do (at this point in time) better. What people call "gut," is not a faculty but a tag for unconscious thinking based on experience. Emotions are the motors of thought. Expert systems and AI are not like human thinking precisely because they do not have human emotions. What will serve as drivers to compel programs to the necessity of making intuitive leaps, then drawing conclusions upon unclear parameters is unkown. Which is why if and when such programs are devised, they will surely have "emotions" unlike those of human beings. Hence, as I said, AI should be read "alien intelligence." Another way of putting it is to recall that "consciousness" can be substituted with "point of view." How can a CPU have a human point of view? How can its sensorium possibly be like that of a hairless primate?

Re: David Brin's latest novel, and a TED talk
I'm of the mind (ha!) that the mind is an emergent property of the neuroelectrochemical processes of the human brain. There may very well be a QM component--we just don't know. What we do know is that the "mind" doesn't just happen, it is the result of years of cognitive development and feedback processes. A newborn baby doesn't have a mind as we understand it--it is not self-aware, and it understands nothing beyond its basic biological urges. As its brain matures and develops, as it experiences and explores the world, it eventually gets a sense of what it is--that is, a thinking, feeling, person of will. Toddlers can't articulate this, but they demonstrate it through their behavior. So, to replicate this, do we just need to simulate roughly the same number of neurons, throw some sensory equipment at it, and let it run for a few years? Will that give us something similar to a human mind? I suppose it's a possibility, but for the most part I doubt it. Likewise, I don't think we are anywhere near copying a mind. Sure, I guess you could map a given brain's neurons and their connections and replicate that in a computer, but there is no reason to believe that would give you something resembling the functioning mind of a person.
I think, if we did turn our decisionmaking over to a highly advanced computer, we wouldn't like the sorts of decisions it would make. (See just about every science fiction book/film that deals with AI for examples, heh.)

Re: David Brin's latest novel, and a TED talk
A lot of AI research used to concentrate on replicating the ego - it's what would really be examined by the Turing test. Is self-awareness actually intelligence? Forget Zen; even some behavioral psychologists would debate that.

Re: David Brin's latest novel, and a TED talk
PS Forgot to actually say "something smarter" could include quantum computing. If they can make that fly, Moore's Law would be an understatement.
