The reason I'm keen about this is that even philosophers
gave up what they called the "mind-brain identity theory"
long ago. Which said that the mind simply is the brain.
The main problem with it was that there is no strict
mapping between stucture and function: capability lost
due to brain injury can be regained, even though the
brain has not regenerated. The next step (though it
still doesn't go quite far enough for me) is to say that
the mind is the functionality of the brain, what the
brain does. Which actually makes a hell of a lot of
sense, if you think about it. Just as two different PC's
can run the same program, so two different brains can
have the same idea, or host the same meme. It's the
logic that matters, not the neural-level details of how
that logic is implemented.
All of which doesn't begin to account for subjectivity,
but at least it's a step in the right direction.
