It is a trite point, but I can't help repeating that, given how very
little we know about the
brain's deeper workings, these estimates of the brain's computational
and memory capability
are all kinda semi-useless...
I think that brain-inspired AGI may become very interesting in 5-20
years once neuroscience
has advanced substantially. At that point quantitative estimates of
neural computing power
may also be meaningful!

This one is quite good, too:

You might find the authors have a bit more credibility than
Moravec, and especially such a notorious luminary like Kurzweil

I'm not actually just being flippant, the AI crowd has a rather
bad case of number creep as far as estimates are concerned.
You can assume 10^23 ops/s on 10^17 sites didn't come out of the
brown, er, blue.
your estimates, I may quote them as well.
Why a workstation? Why not a 10^9 CPU cluster?

memory bandwidth you won't get a lot of refreshes/s on your

Where did *that* number come from?

My neocortex firmware is way out of date, mine unfortunately doesn't
come with procvfs. Time for a reflash...
