There's a big difference between the old fully
manual stop motion, and the last few years, when
it was done with computer driven stepper motors.
Some scenes you might not have realized were stop
motion used stepper motors to drive cameras over
miniatures to mimic aerial shots, while models
of vehicles etc were shifted between frames using
linear displacement gadgets. Sounds complicated and
expensive, but the hardware could be reused for
lots of different shots, so the cost was dispersed
over multiple projects. I expect a lot of that tech
would have been used with the Blade Runner models
which were posted a while back. (A lot of these shots
you might think could have been done in real time,
but the stop motion makes a much smoother result, with
better control, unlike old '30s movies where you can
see model motion mechanisms catching and jerking
as objects are pulled along.)

I once stumbled into this whole field mostly by
accident when interviewing for a job which turned out
to be with a company that did this kind of stuff,
in the early '80s.
