[ExI] cool! locals create circuit board modeled on the human brain

[William Flynn Wallace]

Indeed.  We want the computer to do far more than our brain is doing.


How is it better to have one computer do thousands of things at one time
versus several (or however many) computers dedicated to doing one thing
well?  Seems you'd have a nightmare to debug one doing so many things?  (no
one yet has answered my question about a computer programming itself)  bill
