I guess taking the statements out of context loses something. John, if your response was indended for the "how to connect" part of the statement, then I've misexpressed myself.

The problem isn't "wiring them together" but having them "do something" once wired. Nobody has ever had a 70 million cell neural net before. How deep do you make it? How broad do you make it? How many inputs & outputs should each neuron have?

I'm not sure how flexible the de Garis architecture really is but if the depth can be up to 10 deep, and the net has 1000 inputs and 100 outputs, and each neuron can interact with 500 others, the possible number of configurations is huge.
