You didn't answer my DERP.
Most of what you said is pish. Autonomous AI, as in a program that acts and thinks like a human in every way, is impossible.
Replicating decision making and other 'human' actions is possible, the brain works like a computer, it acts on quick logical decision making based on instinct and experience. Intelligence isn't really a thing as such, you can break down various components of it and replicate it in a program (driving, games, vision, language, etc). What gets tricky is things like personality/character and other human traits, but that's not really 'intelligence' as such.
Basically, you can program computers to be better than humans at most tasks. You just can't get them to want to be an astronaut or like chocolate.
...or be artificially intelligent.
