youtube vid recommendations that are not slop pls

see title... i just realized that for the past few months ive been watching slop videos that dont need me paying attention or thinking at all and honestly its taking away my literacy lmao. i just feel sad because i see the contrast in my liked videos on youtube when i scroll far enough. it went from videos to lemmino or nexpo and documentaries in general to trash commentary content about the most basic stuff.

can people who watch videos with actual substance please recommend me some of them. channel recommendations are also highly appreciated, altho i already know the big names in the industry like stated above.
