Here's where things go wildly wrong:<p>> Since computers don't have bodies, let alone sensations<p>Computers are not non-physical, they definitely have bodies (the physical machines which include the circuitry for executing their software and its necessary support mechanisms); they also can, and often do, have sensory systems providing inputs regarding the state of the world both external (e.g., cameras, microphones) and internal (e.g., temperature sensors) to their "bodies".<p>It may be that the "bodies" of current computers are structurally dissimilar to human bodies in ways which are detrimental to human style cognition -- its certainly true that they aren't build on the same kind of biomechanical design and it may well be that the web of biomechanical feedback loops in the body is important to human intelligence and isn't readily simulated in systems using the technologies used for modern digital computers. But even if that's true, it doesn't say we can't have AI, it just means our AI may need to be built on adifferent set of technologies, e.g., perhaps using biological rather than silicon substrates. But engineering biological systems is something we <i>can</i> do, and with increasing facility.<p>The belief that AI is physically impossible -- rather than just a very hard engineering problem -- is equivalent to the belief that intelligence is, itself, not a phenomenon governed by the laws of the physical universe, but magic that intrudes effects into the physical universe from outside that cannot be reproduced by physical means.
