Analog, yes.  And, of course, everything is ultimately a quantum process,
but neither of these need to be a problem.

: What we do know makes a neuron sound like a finite state machine,

The firing may be boolean, but the threshold sensing with its analog
accumulation bring it beyond "finite".  Again, no problem.

But, you're actually talking about a _lot_ of hardware to do an accurate
simulation for uploading.  _Really_ a lot.  Not no $20/month for at least
75-100 years, even at current price/performance progress.
