There seems a bit of an acceleration ~ 50-100k years from evolving brains similar to modern ones to agriculture, ~8k year from there to writing, ~4k to the printing press, ~400 till computers, ~40 till the web and so on. Each of those has kind of speeded intellectual progress and AI will probably be another speeding up.

A fun way to look at this is that the "long head" (ramp) of the singularity began some hundreds of thousands of years ago. We're just living in teh exciting bit.

Many tens of millions if you want to start with the emergence of primates, etc.

Maybe. I can imagine a dystopian Idiocracy type future where everyone is the "ideas guy".
