Ok, fair enough. (Although I still think you really need to work on your
level 3/4 distinction. You haven't thought about that lately?)
However, this raises the question:
What in level 2 makes the thinking possible? You mention "artificial
(non-bio) life", but what *is* that? Would it be self-healing and
self-reproducing machines? But then what? What would self-healing and
self-reproducing machines have that other machines don't?

Ok, I see. Yes, that's a different beast. However, if we claim that they
can support level 4 ideas, we must show how such simple devices can do
that. I.e. how those level 4 ideas are supported by lower levels.
