It's important to remember though that the "wetware" actually changes
the topology of the brain. It's more like an analogue than a digital
computer in this respect, it rewires itself all the time.

There isn't the clear distinction between hardware and software that
characterises the digital computer.

And, BTW, I still don't see any reason to believe consciousness is part
of the mind.
