Cheating a bit (know them for longer, but they have to be underhyped despite their size):
Subject Zero Science (193K): super well produced bleeding edge science explained. https://www.youtube.com/channel/UCRXRbi80k0_vcIfgpOSerTg
The Thought Emporium (746K): Bio hacking and DNA editing. https://www.youtube.com/channel/UCV5vCi3jPJdURZwAOO_FNfQ
I believe these also correspond with an actual course, although I can't find a link.
Eventually I'll probably share the whole kit & kaboodle with Hacker News. Have to make a proper writeup though (because people are impatient and won't sit through dozens of videos to get the whole story from the beginning haha)

They take the time to make quality videos (even if it takes week or even months) as opposed to others that rapid fire publish videos.
Some channels I'd previously recommend had quality drop. Rather than investing in a topic they got a spammy feel to them.
This German gentleman rescues broken stuff from the scrap yard and repairs it. On this video  he upgrades a basic welder to increase the duty cycle. I specifically like the way he describes his upgrades using diagrams and basic explanations. Link to his channel at .

There's a LOT of "play with X, do activity Y, do this cool thing Z" videos that my kiddo loves to watch while also playing, but could be taken to the next level EASILY.
The fact that PBS and mainstream kids networks don't do things like this, or a more professional production network, is strange to me.
Likely professional production is poison pilled by preassumptions of previous programming paradigms, or the sponsorship fundamentally ruins it.
I myself sometimes participate their weekly open mic sessions.
Feels perverse to me
