I have an absolutely opposite opinion. YouTube is fantastic. If it's bad for you, it might be your own recommendations (which are driven by what you watch).
It's now a fascinating ecosystem with everything from streamers with 1000 followers to people rebuilding cars from scratch with 1M followers to MrBeast.
My own recommendations feed is basically just cooking, hiking, photo, animal videos.
It still works well in terms of discovering content. Most of the channels I follow I found on YouTube. Just recently one of the streamers I watched hit 100k (I remember him at 2000).
