1. There's a lot of superhuman AI out there already, just in narrow domains like protein folding, chess, and so on.
2. Doctorate (and postdoc, and professoral) level responses were already in the training sets.
3. Aim of current AI research is to create a model of the underlying reality which produces the observed signals — what must a PhD candidate have observed for them to write that particular paper, etc.
I have no idea if these AI efforts will succeed or not, hence no idea where we are on the S-curve. But that's the goal.
1. Protein folding is not AGI, and its a technology (much like, say, telecommunications), which no human on their own would be able to perform or even expected to.
3. How can an AI (in a general sense) create a model of underlying reality if the humans who create them do not have access to underlying reality but only the forms of its appearance?
