Your core claim seems to be that the future of AI is impossible to predict for anyone, including Bostrom. If that's the case, it seems like that should inspire more caution, not less.
(There's also some DH2 http://paulgraham.com/disagree.html http://paulgraham.com/disagree.html level stuff about the terms Bostrom chooses to use to make his argument... I'm not sure if there's anything to be said about this except that Bostrom's book seems more accessible to me than most academic writing http://stevenpinker.com/why-academics-stink-writing http://stevenpinker.com/why-academics-stink-writing and I'd hate for him to receive flak for that. It's the ideas that matter, not the pomposity with which you communicate them. I also don't understand the implied disregard for anything that seems like science fiction--what's the point in trying to speculate about the future if all the speculation will be ignored when decisions are being made?)
If an Oxford philosophy professor is not enough for you, here's a succinct explanation of the AI safety problem & its importance from Stuart Russell (Berkeley CS professor & coauthor of Artificial Intelligence: A Modern Approach):

- vonnik 11y agoMy core claim is that Bostrom doesn't know his arse from his elbow. And a professorship in philosophy at Oxford is not, in itself, a great support for his authority on technical matters, or on the behavior of intelligent species yet to exist. That is, in fact, a topic on which no one speaks with authority. I have nothing against science fiction, but I object to any fiction that disguises itself as non-fiction, as Bostrom's often does. Nor do I think that the impossibility of predicting the future of AI is, in itself, a reason for undue caution. Bostrom is performing a sort of Pascalian blackmail by claiming that the slight chance of utter destruction merits a great deal of concern. In fact, he is no different from a long line of doomsday prophets who have evoked fictional and supposedly superior beings, ranging from deities to aliens, in order to control others. The prophet who awakens fear puts himself in a position of power, and that's what Bostrom is doing. Regardless of Bostrom's motives, we as humans face an infinite number of possible dangers that threaten total destruction. These range from the angry Judeo-Christian god to the gray goo of nano-technology to Peak Oil or Malthusian demographics. In each case, the burden of proof that we should be concerned is on the doomsday prophet -- we should not default to concern as some sort of reasonable middle ground, because if we do, then we will worry uselessly and without pause. There is not enough room in one mind to worry about all the gods, aliens, golems and unforeseen natural disasters that might destroy us. And you and I both know, most if not all of those threats have turned out to be nonsense -- a waste of time. I do not believe that Bostrom carries the burden of proof well. His notion of superintelligence is based on a recursively self-improving AI that betters itself infinitely. Most technological advances follow S-curves, moving slow, fast and slow. Bostrom does not seem to grasp that, and cites very little evidence of technological change to back up his predictions about AI. He should be, first and foremost, a technological historian. But he contents himself with baseless speculation. We are in danger, reading Bostrom or Russell or Good, of falling into language traps, by attempting to reason about objects that do not exist outside the noun we have applied to them. The risk is that we accept the very premise in order to fiddle with the details. But the very premise, in this case, is in doubt.
- astrofinch 11y ago>That is, in fact, a topic on which no one speaks with authority. Agreed. >Nor do I think that the impossibility of predicting the future of AI is, in itself, a reason for undue caution. Sure. >Bostrom is performing a sort of Pascalian blackmail by claiming that the slight chance of utter destruction merits a great deal of concern. In fact, he is no different from a long line of doomsday prophets who have evoked fictional and supposedly superior beings, ranging from deities to aliens, in order to control others. The prophet who awakens fear puts himself in a position of power, and that's what Bostrom is doing. Consider: "Previous books published by authors hailing from Country X contained flaws in their logic; therefore since this book's author came from Country X, this book must also have a logical flaw." It's not a very strong form of argument: you might as well just read the book to see if it has logical flaws. Similarly even if a claim seems superficially similar to the kind of claim made by non-credulous people, that's far from conclusive evidence for it being an invalid claim. It would be a shame if religious doomsayers have poisoned the well sufficiently that people never listen to anyone who is saying we should be cautious of some future event. >And you and I both know, most if not all of those threats have turned out to be nonsense -- a waste of time. Sure, but there have been a few like nuclear weapons that were very much not a waste of time. Again, you really have to take things on a case by case basis. >His notion of superintelligence is based on a recursively self-improving AI that betters itself infinitely. Most technological advances follow S-curves, moving slow, fast and slow. Bostrom does not seem to grasp that, and cites very little evidence of technological change to back up his predictions about AI. He should be, first and foremost, a technological historian. But he contents himself with baseless speculation. I can see how this could be a potentially fruitful line of reasoning and I'd encourage you to pursue it further, since the future of AI is an important topic and it deserves more people thinking carefully about it. However, I don't see how this does much to counter what Bostrom wrote. Let's assume that AI development will follow an S-curve. This by itself doesn't give us an idea of where the upper bound is. Estimates suggest that human neurons fire at a rate of at most 200 times per second (200 hertz). Modern chips run in the gigahertz... so the fundamental activity that chips do is being done at something like a million times the speed that the fundamental activity neurons do is being done. (Humans are able to do a ton of computation because we have lots of neurons and they fire in parallel.) And there are lots of arguments one could make along similar lines. Human brains are limited by the size of our skulls; server farms don't have the same size limitations. Human brains are a kludge hacked together by evolution; code written for AIs has the potential to be much more elegant. We know that the algorithms the human brain is running are extremely suboptimal for basic tasks we've figured out how to replicate with computers like doing arithmetic and running numerical simulations. Even within the narrow bounds within which humans do differ, we can see variation from village idiots to Von Neumann. Imagine a mind V' that's as inscrutable to Von Neumann as Von Neumann is to a village idiot, then imagine a mind V'' that's as inscrutable to V' as V' is to Von Neumann, etc. Given that AI makers do not need to respect the narrow bounds within which human brains differ, I don't think it would be surprising if the "upper bound" you're discussing ends up being equivalent to V with a whole bunch of prime symbols after it.
