Starting this to list a few I like - and have found useful or just uplifting. I spend all too much time watching when I'm sort of incapacitated due to cancer and meds, so why not share the good ones?
Useful: I'm mostly just listing the channels here as embedding the latest neat video would make this page too long - we can do those in replies.
I'd have to list Joe Pieczynski (we just call him Joe Pie) as the top machinist for tips on how to do the near impossible. He really goes there with the how-to and the why, where others mainly just show off.
https://www.youtube.com/results?search_ ... e+pyzynski It's all good.
Blondihacks is a little more of a home gamer and definitely has her own charm. The sharp-eyed will notice she has reloading tools showing now and then.

I really enjoy This Old Tony. He's the best tig welder and perhaps specialized tool builder/modifier out there and no question has the very best Dad joke humor. Anyone who can do this with TIG and Al, well, pay attention, right? https://www.youtube.com/results?search_ ... s+old+tony
Builds his own CNC, modifies old surplus tools to give tenths accuracy. Did I mention he's funny?
Anyone who doesn't admire Clickspring (Chris) has a problem. He's just beyond most mortals, but maybe with a masochistic love of files...

Clocks for billionaires...Antikythera Mechanism, makes authentic ancient tools to make stuff with. Crazy good.
I'm looking at a couple other machinist channels for inclusion but this better get ya started. See ya in a month or so.
There's a lot of negative and too little positive out there.
Daily dose of internet is almost all positive all the time, no matter how lousy the thumbnail is - just click and see. Stuff even I hadn't seen before and am often amazed at.

This guy isn't always about how good things are, but damn if he can't be funny about whatever it is. And sometimes just applauds stunning stuff by someone else, like that gymnastics review.
(not the norm for him by a long way) Ozzy man! https://www.youtube.com/user/ozzymanreviews
And OK, watch this: https://www.youtube.com/watch?v=xfnnGSkJ-2U language not suitable for work, who cares.
I'm studying propaganda and WW-whichever is a great set of sources as more is declassified. They're no better at telling lies now, really, but more is suppressed to make it harder for dummies or potatoes to figure out. The timeghost series of channels - Indy Neidell as the front man - is truly outstanding in this regard, you'll find out all sorts of things not taught in the books written by the winners, or CYA lies propgated by historians using each other for validation and not checking sources.
https://www.youtube.com/results?search_query=timeghost has most of the list. WWII as it happened - like a news channel that just happens to really know everything - is great.
Between 2 wars is fantastic and stuff that is rarely covered but it's where the modern world originated..
War against humanity is often gross - consider what it's about - but it might be nice to remind the current group of communists how Stalin used the same scapegoat trick on Kulaks that Hitler did on Jews - and killed more of them before WWII than Hitler did Jews. Lots more. Old trick - scapegoat any easy identified group doing a little better on average than the rest, get people to hate them, rise to power or hold on to it via helping eliminate them. One wonders if cis white males are the new scapegoats for doing better than the uneducated/don't try hard groups. Ah well, I try not to do politics here, we all kinda know what's what anyway.
Now, for techies...and this is hard to put in any order, they are all so good.
Greg's airplanes and automobiles - primary sources on WWII European theater planes, specs, designs, the why and so on. https://www.youtube.com/results?search_ ... +airplanes
A good foil who has access to German primary sources and complements Greg's views: https://www.youtube.com/results?search_ ... on+history
And then there are warships. If you think about it, you have to run whatcha brung, they take a long time to build pre-war and people tend to not like what a navy costs. Your cards are on the table...
More often than not it's worth waiting for that one line of dry Drach humor that will have you rolling. Especially the long form stuff I adore, the Wednesday rum ration (british tradition).
https://www.youtube.com/results?search_ ... rachinifel Some of the long collaborations aren't up to snuff - some of the helpers know a lot but stink at actually presenting.
Back to things engineering and science...
Tech ingredients is fun: https://www.youtube.com/results?search_ ... ngredients

The best math guy ever. Many of us wish we'd seen his stuff before taking math courses 3b1b (Grant); https://www.youtube.com/results?search_ ... blue1brown
His animations that give you a great feel for how the math is shaped make me think python might not be all bad. That's a really strong statement as I kinda hate python.
He did a great collap with Dianna, "physics girl" who is always entertaining and sometimes correct. Check out square smoke rings...and maybe her channel too: https://www.youtube.com/results?search_ ... ysics+girl
Square ... and you WILL be surprised at the dynamics, which Grant explains on his channel later on. https://www.youtube.com/watch?v=N7d_RWy ... hysicsGirl
Do add your own favorites. It's gonna be hard to live up to these but I'm sure I haven't seen the whole world yet. I'm not even sure I'm done, I have limited brain capacity just now.
Unlike what Grace Slick of the Jefferson Airplane sang - "the ones that mother gives you DO something at all" now. Hope to get off of those soon.
