History matters : he makes short 3-4 minute videos about interesting historical topics also his 10 minute history series was amazing I highly recommend it
Since you liked pointless hub you should check out alternate history hub it’s owned by the same guy and his what if scenarios are amazing
Technology Connections explaining how TVs, refridgerators, coin operated record players, LaserDisc and any kind of other technological stuff works
Lemmino documentary type videos about all kinds of stuff, not many videos and hasn't been posting for a while but the backlog is good
Fredrik Knudsen documentary videos mostly about internet culture, also hasn't posted for a while
Obviously Tom Scott, but also the channels with his friends Matt and Tom (no new videos anymore, but has Citation Needed and Two of these people are lying) and Technical Difficulties
If you like Fallout/Skyrim/Dark Souls (and other games of that like), check out Ymfah. 10/10 for the insane challenges that dude puts on himself. Didn’t see him in the list, easily my favorite to watch when I’m bored
Numberphile is great if you're interested in logic and math. Their older videos are best, so it's a bit of binge watching if you've never seen them before. You don't have to be great at math or anything. Every video basically starts from common logic.
If by any chance you're interested in music, I can recommend Paul Davids, who is just another handsome guy with an acoustic guitar, but actually manages to dig deep down into both the theory and techniques of good songs.
If by any very odd chance you'd be into skateboarding as an adult, I'd recommend Jon Bishop, who is an old dude going through all the steps in a safe manner. The bonus is that whenever I watch any of his videos there'll also be many good suggestions from that.
Fraser Cain - he goes over everything space but without the physics. Very down to earth and very real scientific space talk. Also goes over weekly space news.
And if you want more of the physics side, pbs space is also great as well.
