But you have to acknowledge how uneven the playing field is. The AI has read every book that's ever been written, and can spend hours of compute time in a few seconds.

I think if a person had those same advantages (e.g. could spend 5 hours thinking about what to say next) we could all hold outstanding conversations, or if we had read every book ever written I think many of us could write a very popular book, if we could read every singe company's P&L statement in a few seconds we could invest better than an index fund.

What I'm pointing out here is that these models appear to be intelligent when they really are simply unimagineably knowledgeable. When you drop the time-constraints it starts to become more and more apparent that human intelligence scales better with time than AI does (much in the same way AI can burp out tons of code but make your codebase entirely illegible within a matter of months).

Perhaps to simplify: my notion of intelligence is how much can you deduce with a constant set of starting context

I would be willing to bet that any human for which we spend $100billion - $3 trillion (depending if you want to count single corporations or global totals) on in an attempt to make them as capable as possible would be able to reach all of those levels.
