Well one must also argue the opposite. I myself have gained immense knowledge from YouTube. I have learned things like phone screen replacements or phone battery replacements. I call myself a mechanic from the school of YouTube and have saved myself at minimum $10k in repairs doing the work myself. I have learned to make endless food recipes or create things like giant bubbles or slime for my kids. My point is that I bet sure for some YouTube is a massive time sink waste of time. But I also wonder how much it has improved the knowledge, skills and ability of others.
My dad often mentions how had he had YouTube when he was younger how much it would have done for him. He talks about having to go to the library and if lucky there was a book that could show you the knowledge you were looking for. He says but now you can find not just the knowledge but for example specific knowledge like car make model and year and how exactly to do job xyz.
Ultimately I just can not imagine life without the wealth of knowledge YouTube has given me.
Lol I laughed out loud reading this comment. When shorts first came out they annoyed me to no end. I searched for how to block them through settings or other ways to just make them go away.
But now days I can admit there are a few, very few, content creators who create shorts that are very informative and straight to the point that can cover a topic and give you many facts and let you decide if you want to seek more. Sometimes it is nice to have the 30 seconds Coles notes verses a video stretched out to 10 minutes to be eligible for monetization.
BUT, and this is a big but, the shorts and similar video platform trends scare me as a parent. I can see how my kids find a 1.5 hour movie boring but can scroll endlessly through shorts. It might seem harmless letting your kid just scroll on YouTube from my perspective is like an addiction and kids are getting that dopamine hit watching a clip and seconds later watching something else. I've learned that it is very important to be aware of what your kids are being accustomed to and push them in the right direction.
Personally, I just scroll through them. They break the feed into well defined "chapters" at the end of what I can decide to look into the next one or go somewhere else because there's nothing good there today.
Also there's this woman that makes very funny shorts about software development and good long videos that aren't as good. I look for her shorts too.
