Should Greenhorns Care About The Way Things Were And How We'All Got Here?

I've been reading this book CCTV:From Light to Pixels by that cctv guru Vlado Damjanovski. It's a dandy of a read, if you don't have it, get it!

But one thing though that Mr. D does over and over is to go way back in time to start his lesson - and I mean way back! For example when teaching CCTV cameras he starts with them glass tube cameras, for a good five pages! By which time you have forgotten the transistor was ever even invented.

He apologies, sorta, after these nostalgic flashbacks, saying something like "it's really good for newcomers to understand the history of technology, it pays off in the end."

Y'all think so? Maybe the time be better spent on learning about 4K technology than the relics like how long the NTSC line blanking period is. (10.7 us) And if we should go back, how far do you gotta go? Bell?, Edison?, even Lindgren?*

Ask that next whippersnapper tech to replace a vacuum tube for y'all. When he opens up the Shop-Vac, don't hide the sound of all the air in your body escaping at once...
