A real-time history is probably the usual and the optimal way of
getting those things into a head, but if the current state could be
built in directly, without a real-time history, would that make the
system any different from what it would be if it had earned them the
On the other hand, for T3 (or even T2) passing, there has to be a
forward going history, starting from whenever the Testing starts. The
capacity for interacting in real time is part of T3.

It is not implementation-independence that is at issue with real-time
history. But symbol grounding might be part of what's at issue.

Never mind "self"-awareness. Settle for any kind of awareness, e.g.,
what it feels like to be pinched (which even a worm could have). Yes,
that is what having a mind is. And although it is true no one has a
clue how symbol-processing could generate feelings, no one has a clue
how anything else (including brain activity) could do it either!

It's one thing for it to be true that a mind really does piggy-back on
computation. Maybe it does. But is for: How? Explaining that is the
