I've seen that zombie behavior too when my kids watch too long. I think there's definitely value in some shows, and some of them are actually very educational. I think there's a lot more variety these days than when I was a kid.
As a rule we don't allow Blippy because the man creeps me out, and something about his childish behavior rubs me the wrong way. OTOH the other day my 5yo kid asked me if I knew why the sky was blue. I genuinely wasn't sure and he somewhat explained what he learned on TV from a show about sunlight and particles in the air.
100% agree on Blippy, the vibe is very off for me. Especially once I learned about his history as a shock youtuber[0], I'm glad that he says he's grown past that and regrets making the content he made but his content is tainted (pun intended) forever for me and I'm not interested in exposing my kid(s) to that.
