For me I really do enjoy watching some of the Locking picking lawyers content and he is an expert when it comes to picking locks!
Another few are mental outlaw (although I think everyone knows of him here) and Steven Bridges who makes videos on card counting at casinos and he shows how much he wins/loses from playing
Brick Immortar - does very neutral, safety oriented breakdowns of maritime disasters (mostly) I love his narration, he speaks with a ton of authority imo and I find all the procedures and rules of ships fascinating.
Animagrafs - modern marvels but shorter and on 1 topic. Extremely professional animations of big ass machines. He just did one on Big Boy steam locomotives and it was amazing to see the systems work.
The Squidd - does video essays on famous cars and their histories
Game makers tool kit - following his journey of learning game development
History of the entire universe - incredible free documentaries about the deepest and craziest topics about our universe and reality. I listen to them to sleep
I did a thing Backyard scientist William Osman ^science YouTubers, menaces
Marcus house - following along with space progress, specifically starship.
No clip - video game documentaries
People make games - interesting stories about gaming, very professional deep dive stuff (Roblox is the devil)
Regular Car Reviews - bizarre car reviews with a goofy narrator who makes a ton of literary references I think he used to be a teacher
Secret Base - sports stat nerds (watch their scoragami and worst NFL punt videos)
Technology connections - learn how genius some of our everyday inventions really are
Zack Freedman - ADHD tech maker 3d printing nerd
