Then every system ever made that has the concept of a master timing clock,
including TV and the computer you are working on, is "an extremely fickle
system that lacks robustness".

The concept hasn't changed over the years, just that we have progressed from
R/C oscillators to crystal oscillators to GPS.

Perhaps you think we would be better off if such systems had a master
crystal osillator somewhere with coax to every remote system to keep
them all in sync?
