Its because the Bob Pease video fills a deep seated desire in the engineer heart.
We almost wonder if it might survive the fall. Of course we could SIMULATE the
trajectory, but sometimes the more straightforward approach is indicated.

I do recommend simulation. It can spot a stupid mistake that you might not
notice.  Usually (with a little real world experience) you CAN tell when its lying,
or at least giving you a too optimistic result.

One fun thing I noticed about the Moog ladder filter simulation... running frequency
response plots while increasing "Q" gives the more and more pronounced peak...
but then suddenly the peak gets much smaller. Any guesses why that is ???  :^P
