Forward-engineering the brain:
Build an F-eng robot that passes the Turing Test:
It can do everything a real human can do,
for a lifetime,
indistinguishably from a real human
(except appearance: we will return to that).

Is it really conscious?
It is indistinguishable from us
in everything it can do.

But conscious is something I am,
not something I do.
In particular, it is something I feel;
indeed, it is the fact that I feel.
