It's so easy to see that this guy is wrong. I have a masters in IA, but anyone if a decent CS degree will agree that we made almost none true evolution in computers since day one. All we did until know is make it faster (and easier to use), but the type of problems we can solve (math wise) today is exactly the same kinds a turing machine could (in theory) solve in 1936. EVERY problem today can be simplified to a turing machine code somehow.
We are still trying to make a quantum computer, which could in theory solve some kind of problems our current computational approach can't.
Every time some guy in the IA field says that the problem is computer power, just ignore him and move on.
Actually I have a lot of respect for Industrial Arts majors.
