Ummm, but isn't Moore's law only two or 3  process shrinks away from being  
stone cold dead?
After that it's 3D chip stacking, with the significant difference that  
each layer costs in both resources and cycle times to fabricate the device.
And to make matters worse, power consumption and heat dissipation only get  
worse with each additional layer.

So no more Moore's law to magically make uploading any easier or cheaper  
for everyone sometime down the road.

So how many super computers can this future energy grid support?
