I agree. Buy I expect we will have to unravel all of the mind-boggling,
inefficient complexity of the existing system before we understand its
behavior well enough to make a more efficient replacement that accurately
duplicates its behavior. Otherwise we'll end up with inaccurate simulations
that don't work.

Not in detail, no. But that doesn't mean we can just dismiss the subject,
because it is obvious that there is a lot of potential for significan
tinteractions. Until we have a better picture of those interactions (which, of
course, means a lot of difficult research), it is going to be very hard to
assess the plausibility of any particular technology scenario.

That URL doesn't seem to be working, but I beleive I remember the paper. As I
recall, you analyzed the effects of rapidly adding uploads to the labor pool
in considerable detail. However, your analysis focused exclusively on the
supply side of the equation - there is no consideration of the fact that the
uploads also contribute to agregate demand, which would tend to offset the
downward pressure on wages.
I also think that your 'fast, cheap copying' assumption is an artefact caused
by projecting a very advanced technology into a world that is otherwise
unchanged. If uploads actually existed today, copying one would be a
multi-million dollar operation involving weeks or months of work by a team of
highly-paid specialists. A future where uploads can be created and duplicated
like text files is a future where virtually everything important is software,
and therefore capable of equally rapid duplication. It is also a world right
on the verge of full-fledged mental modification technology, which takes us
beyond the realm of easy prediction.

Considering how limited our ability to train animals is (compared, say, to our
ability to 'train' computers), that is hardly surprising. Robots are a rather
different case.
