The general idea won't change. If we take away the housekeeping
functions we'll have left over even more of what makes us
smarter than the other animals.

Say what? ARe you one of the quantum brain enthusiasts too?
The mind is what the brain does. What ever the brain does,
electro-chemically is sufficient to produce mind.

It's hard to tell. There are better results when the chip
brains are compared against humans than if we try to find
corresponding parts in dog brains or reptile brains. They
probably don't have or have very little of what we possess.

Yes, good point. It's a stinking field when you start to ask
important questions. Most of it is guessing. In time, there
will be more answers.

Yeah, right. Bacteria are :-).. OR is it banana trees??
