The problem is also that the rate of, and ease of production of terrible content far outpaces good content. So it does matter that there’s loads of junk because finding something worthwhile gets hard very quickly.
I guess it depends how good your search is. Bit of an ongoing battle. Like I was on youtube last night looking at some stuff about problems with the UK economy and thinking the quality is really rather good - the best was probably a C4 produced doc with Tim Harford. But there is a lot of clickbait dross on youtube also. For some reason I get about ten different 'why it's all over for the Cybertruck' ones which doesn't really match their content saying it's basically ok.
