Any topic where being an expert is not mere memorization or imitation without comprehension, and discovering new facts is not just relentlessly churning through a rule set and producing what was already self-evident. I don't disagree whether computers are good at computation. That's what they're for. I disagree that AI can replace experts because expertise is a moving target. Where AI approximates a response given at some point in time or within a range of time written by a crowd of people who are not necessarily experts, experts must inevitably contradict themselves on something and update their theories. AI as currently implemented will always lag behind human experts. In other words, do you seriously believe that an AI trained on scientific publications from the middle ages would eventually rediscover what we know now and beyond? I think it would be stuck forever hallucinating recipes to turn lead into gold.
