I find some media to be actually helpful if it is instructive. I frequent YouTube for how-to videos all the time and there are tons of videos that have saved me time and money by making rookie mistakes that someone more experienced in a particular field mentions off-handedly in a video. It's great for software projects, electrical engineering projects (like Raspi and Arduino stuff), and a lot of other miscellaneous things where people with hands-on experience can share tons of wisdom in short video.
That said, there is also a lot of junk YouTube content, which feels similar to browsing Reddit, Facebook, or eating donuts for that matter... It's a guilty pleasure to watch some videos. Even the "cute" ones, like cat videos, or "funny" fail compilations, or impressive parkour videos. These can be entertaining on the surface, but I find they do the opposite of inspire me. They're temporarily exciting to watch, but overall do not any value to my life and in the big picture, I find them to be more of a distraction than anything. Some people have a balanced media diet and can consume it moderately. For me, it's too easy to spend several hours in any given week watching completely useless videos - especially with the ever growing mechanisms to try to keep your eyes glued to the screen (auto-play features, suggested playlists, etc).
I compare it to a type of drug use. Some people handle it well, others don't. Like most things, YMMV.
Edit: I also feel like with YouTube's insane growth over the past decade, there are way too many people trying to game the system. It leads to some very good content, but also a lot more junk content that just manages to add better keywords for searches, or a more attractive title/thumbnail to catch your eye (I'm sure many people are familiar...).
