[extropy-chat] The Inevitability of Universal Immortality

[Hara Ra]

Each "synapse" is a small emulator intended to handle these things. In the 
worst case, such an emulated synapse would be about the same volume as the 
original. I did not say all 'synapses' were identical, was only doing a 
volume estimate. I do my best to say what I mean, but I cannot handle 
assumptions provided by others. So thanks, now you are updated.

When nanoscanner examines synapse, would set up model parameters from data 
therefrom.
