I’m mostly into educational channels:

• CGP Grey (infrequent posting schedule, but really good when he does)
• Minute Earth (Quick Earth science videos)
• Minute Food (Quick food science videos)
• Technology Connections (explains new and old technologies)
• Kurzgesagt (general science with cartoon birds)
• Mark Rober (over the top engineering)
• The 8-bit Guy (retro computing and pc gaming)

Then there’s “You Suck at Cooking” for silly, but good recipe videos.

“Film Joy” for deep dives into films

“Lock Picking Lawyer” to watch a guy pick any lock in a few minutes (addictive)
