Then you need a more precisely framed question.
1. AI can do what we can do, in much the same way we can do it, because it's biologically inspired. Not a perfect copy, but close enough for the general case of this argument.
2. AI can't ever be perfect because of the same reasons we can't ever be perfect: it's impossible to become certain of anything in finite time and with finite examples.
3. AI can still reach higher performance in specific things than us — not everything, not yet — because the information processing speedup going from synapses to transistors is of the same order of magnitude as walking is to continental drift, so when there exists sufficient training data to overcome the inefficiency of the model, we can make models absorb approximately all of that information.
