I basically agree, I have. My account of my limited experience is above. I never managed to get recommendations beyond kids dancing to pop songs with their dog

Strange. I see things like

• quality original skits & memes

• craftsmen making shorts about things such as the assembly process for a certain furniture

• doctors showing day-in-the-life videos as well as quick health advisories and PSAs

• remixes of existing music and indie artists promoting new music

• experts in niche fields, ranging from logistics, to theoretical physics, to law, to carpentry make quick, shallow-level explanatory videos of things that interest them

• everyday Joes essentially vlogging about interesting things that may be unique to them (like a medial condition, situation, or something else)

• … and yes, dancing teenagers.
