Polymatter - mostly about company / nation scale economics. Possibly too high-level for the average HNer.
Mustard - great videos about the history of notable vehicles - mostly planes, with a couple of trains. Mixture of historical footage and great animation.
Journey to the Microcosmos - very new channel, basically little nature documentaries about microorganisms.
Robert Miles - really great videos about AI safety - why it's important, what the cutting edge of research is etc.
Captain Disillusion - VFX breakdowns of hoax videos and some explanations of video technology. His channel also hosts videos of a couple of his talks, which are excellent.
Tom Scott - five minute videos from interesting places, plus some layman level programming topics.
Jay Foreman - mostly maps and politics combined with British humour.
TechAltar - Tech company strategy discussion - some normie topics, but some interesting insights as well.
Internet Historian - very well made videos about significant events in 'Internet Culture'. Famous/signifant 4chan raids, cons that went badly and other misc stuff like Fyre festival and the launch of Fallout 76 that spawned a lot of discussion and memes. Definitely not for everyone.
I'm not sure whether you'd consider review channels educational but if you do then I like:
