I'm looking at the right level to be probably adequate to track
information-processing relevant changes in the space between our
ears in the right time frame (~1 ms). It might be not enough, it
might slightly too much, but it is very many orders of magnitude
removed from a PC to illustrate why it's ludicrous. Why a PC? Why
not a pocket calculator, like TI-83? I mean, where's the limit?
The whole field of AI is full of ridiculous pronouncements like
this. Even these wild-ass guesses show a distinct number creep

It currently takes a Blue Gene to (poorly) model a very crude model
of a cortical column. Not exactly in realtime.

Can I see a realtime model of your cortical column on a PC?

You will not fit a human hardware equivalent in a rack by end of
this year. Or in ten years.
