Are Bypass Capacitors REALLY needed?

Dave Jones doing another interesting video.

It touches on PCB layout issues vs noise, that is what I spend a lot of time fighting on the ST!

I really don't see what was the point. Are such videos REALLY needed ? Some people benefits from them, for sure.
I did not hear everything new. Both things are important - layout and capacitors. But it's much better to have them as much possible close to chip pins. I often solder them there directly. Even CPUs in modern PCs have some capacitors built in, for best possible effect.

For people who don't know basic electronics, then sure, video is useful.

His vids are always gonna be controversial, if I wanna watch one of his vids, I rip it, then drop the audio by an octave lol. He's a bit anal at times, but not as bad as that Carlson guy, man is he verbose.

I don't watch all the vids, but he does tend to waffle on fair bit. Though probably better for more beginners, I'm just sat saying "get to the point" mostly, Though I am more of a facts with bullet points person, says me, :lol:

It's just that you need to watch half hour long video, or rather talk with little video, often some commercials, to maybe learn something what can learn after 2 minutes of googling and read some article - max in 5 minutes.

I dunno about you guys but I find myself editing on the fly (L to fast forward 10 seconds on YT) just to get past a lot of spiel that's not needed, or to bypass repetitive stuff. Also the Wadsworth consonant is real. If it's someone I like listening to, say big clive or ave, I'll happily sit and listen, but for general vids wher you are looking for definite solution to a problem, most of it is junk, and filled with "uh" and "erm" etc.
