Garbage In: Garbage Out.
That’s what AI is all about.
It depends on what you are putting the garbage into, doesn’t it? If I take a bowl of oatmeal, add a little butter and sugar to it, then drop in a few multi-vitamin capsules, I will have before me a substance that is both chemically and physically similar to a human brain; but it cannot think, recognize patterns, or solve even a simple problem, no matter the quality of my input. The mystery of consciousness, which is not yet even vaguely understood IMHO, is how these so similar combinations of physical substance behave so differently: one merely sits there and gets cold, while the other can write Hamlet or King Lear.
