no, No, NO. You're not listening. Brain simulations aren't embarassingly
parallel. You'd need some few kNodes, each with <1 us latency, and 
some 10 GBytes/s throughput. On WAN, you'd get some 10-100 ms, and
few 10 kByte/s thoughput.

To be blunt, this kills it dead. You need to use very large scale
distributed resources correctly, orelse you're wasting their

Whoa, whoa, whoa. Once we have these, then we're right in the
middle of that Singularity already. Self-rep is hard, and it's
mostly a control issue on macroscale, and a bootstrap issue on
nanoscale. We can't do either yet.
