[MURG] new Road Map draft

[king-yin yan]

Sorry about the delay!! I'll answer questions bit by bit...

Devil is in the details... Is it possible to have a complete
gradual replacement using such a portable device? I'm
afraid if you got hundreds of millions of wires this is
not practical... With things like artificial eyes that would
be OK.

My impression is that glass microelectrodes are
suitable for single-cell in vitro recordings, not whole-
-brain in vivo interfacing.

If you think about the *whole-brain* replacement process,
we really require extensive interfacing. Let's work out a
scheme of how to do the whole brain replacement.
