My entire subscription feed is hundreds of edutainment channels pretty much. It's my alternative to the discovery/history/science channel for the modern age (and tbh it's higher quality too in many cases)

It's also really really good for learning practical skills like home repairs and automotive maintenance.

Some favorite channels:

Nilered

Styropyro

Practical engineering

Technology Connections

Breaking taps

The thought emporium

I have learned a lot from YT, it's a really good plataform for that. Languages, programming electronics, and the list goes on... that was my YT experience during the 2010s. But there is also a lot of bs out there, maybe fuled by monetization, extreme groups or just because mankind is stupid at its core, that is purely aimed to diffuse nonsense, catch peoples attention or plainly influence people views.

Where I live, revisionism is teach at schools as if it is the real thing. "A part" sometimes is enough.

My comment was originally thought more as a joke than as a real complaint, but in all seriousness, YT has become an extremely good tool both to learn and to influence people. I understand that "regulating it" would be also another double edged sword, but something has to be done.
