> Do you have an objection to this specific statement when taken to mean general human-like intelligence being exhibited by computers? I have not heard anyone defend the opposite viewpoint often, and I'm interested if there are any compelling arguments why it's not possible.

A few aspects which relate and shape intelligence:

1) Socialization; 2) Embodiment (the fact that I have a body and the body has feedback loops - affects and is affected by cognition); 3) Emotions (we have "hunches" and those hunches are surprisingly many times adequate); 4) Language (our sign system affects our perception of the world).

Will a computer be able to be a sociable, embodied person? I tend to think that it won't, so that's roughly why I believe a computer won't ever have "intelligence" (unless, again, we redefine intelligence).

1) 2) 3) Are I think research goals of robotics. None are simple but I don't personally think they require anything that isn't possible to accomplish with computer + physical objects beyond the computer itself.

Any algorithms we use to simulate intelligence with machines are excessively wasteful.

There's not enough energy to simulate human intelligence at the same speed that humans think, without just essentially producing biological computers.

And that's more of bio-engineering than anything relating to computing.
