Nebula is pretty great, I like a few people there. I'm also on YouTube a good bit, but only the channels I subscribe to

On YouTube itself, a few I like:

• Tom Scott, every week is something unexpected and somehow also something I want to know more about (link)
• A Great Big Story: My family really enjoys this one. It's short interesting videos about different places and cultures. I like the ones where the host compares a food/practice from different places (link)
• About Here: Local creator in Vancouver/Canada that does stuff about local issues (link)
• Neo: I think it might be tied to a company, but the videos are interesting and very high quality. I like the 3D renders that they use. This one's also on Nebula (link)
• Babish, mostly the basics series and any foods from shows/movies I've seen (link)
• Jun's Kitchen: Really nice and peaceful cooking clips. Their cats are great too (link)
• Mustard: cool videos with nice renders about historical planes, trains, and stuff. Also on Nebula
• Thomas Flight: nice analysis on movies and TV, for things like visuals and sound design

Otherwise, here is a messy list of some more:

• Captain Disillusion: learning about visual effects and trickery
• Colin Furze: whatever crazy thing he's building today
• EngineerGuy: a bit technical, but interesting
• EuroCarGuy: to fall asleep to, no talking just driving
• Hagerty: also a company run channel, but it's got fun car content
• Ice Cream Sandwich: it's funny
• Kurzgesagdt: watching this one for years
• Memable Data: a recent one, also cool visuals
• Michael Reeves
• Simone Giertz
• Technology Connections
• The slow mo guys
• Veritassium
