hi, i enjoyed reading your comparison between the human mind
and a computer, but i have some 'amatourish' questions.
does your estimates take into account the processing power needed
for the possible information flow in all these 1000 connections
from every single neuron in the human mind?
without knowing so, i assume that a human neuron works with
analog signal levels, is this 'extra' A/D conversion taken into account?
