> 3. ... before too long we will ... see AIs that outperform humans on most tasks. This is ambiguous. Do you mean A. that there is some subset T1 of the set of all tasks T such that T1 is "most of" T, and that for each P in T1 there will be an AI that outperforms humans on P, or B. There will be a single AI that outperforms humans on all tasks in a set T1, where T1 is a subset of all tasks T such that T1 is "most of" T? I think A is unlikely but plausible but I don't see cause for worry. I don't see any reason why B should come to pass. 4. AIs that are much smarter than any human pose even graver dangers. Sure. Why should we believe they will ever exist though?
