Rubbish.

Interesting electronics is nonlinear.

Also rubbish. Most electronics is non-linear, but the interesting stuff does tend to be linear in the regions of interest.

I recall some college professor mumbling about solving nonlinear differential equations but it wasn't
encouraging.

Not encouraging enough to get your attention.

Having some gut-level feeling for integration and differentiation and
diff equations and initial conditions and control theory is good, but
Spice can do the actual work.

Perhaps.

I taught a course once on dynamic systems. The final assignment was to
write a Basic program to simulate refilling a toilet tank after a
flush. Surprisingly, everybody got it right.

You kept the course down to a level that you could understand.
