I think it makes sense. Visual media just work well and universally so for all humans I’d say. All the other limited platforms are stuck with some indelible fashion like a haircut from a certain era and so always show their age eventually.

On top of this I think there’s an argument that YouTube have been uniquely successful in their attempt to take a middle path between profitability and facilitating creators, the result of which is that you get a performant and easy to use service (with a pile of ads) that connects with what feels like a huge range of real people talking about real interests.
