It seems that everything turned into scams, aggressive self marketing and just click bait irrelevant content. I liked finance videos, but every creator sounds like "the world will end soon" or "my secret method to make 1 million per week day trading stocks/forex/crypto."
Content aimed at culture (movies/series) also behave the same way, throwing a bit of politics into the mix. Always the same incendiary click bait title spewing a bunch of nonsense that has nothing the story, setting characters or other topics relevant to the piece.
Is there anything that can be saved on that platform? It has gotten so bad that I'm start to think that Tiktok and Twitter both have better content than YouTube. At least in those platforms you can find a random dude writing an essay in a series of 20 tweets on why an increase of mantis is related to the global surge of ballpoint pen prices.
It's been going downhill for a long time. Popular content do the same as tv-cable network where they try to generate outrage. If the videos I watch start to change in ways I don't like I just move on which is what I think people should do. Decrease in viewership will definitely be noticed. Luckily, the creators I follow have stayed the same where they are a one person or small group who create videos to inform or for entertainment.
