I know, I'm getting addicted to listening to podcasts while simultaneously watching "drivers eye" railway videos. Niche and addictive...Neither cycling-related nor a rant but it intersects with my interests enough for me to reply.
I spend far too much time on Youtube, it's a great place for getting info on niche interests/tutorials for doing things that I would never be able to do otherwise, and there's a lot of clever and creative people using the platform to do fascinating stuff.
However, I think it should come plastered with warnings like cigarette packaging, for two reasons.
Firstly, it's basically an infinitely deep well of content, you will never run out of stuff to watch and you can easily end up spending far more time than you intended. It is addictive and the recommendation system uses a whole bunch of psychological tricks to make you want to watch the next video (since more video views = more ad revenue for google)
Additionally, it's dangerous to rely on it as a source of news, information and entertainment, as there is no editorial oversight whatsoever, which, combined with the tailored recommendations makes it incredibly easy to fall down a rabbit hole of "Since you watched Johnny Q. Seeminglyreasonable here's his next video 'Why Covid is fake news and the planet is flat'" without ever seeing recommendations for videos that provide contrasting views. Some of my previously reasonable friends have been radicalised by these people into believing some truly demented conspiracy stuff.
To quote the end screen from one of my favourite series: "Please note that Evan is kind of an idiot. Don't ever take his word for it. Always research what you see on Youtube. Don't let anyone think for you; most people can barely think for themselves."
(The irony of quoting this text is not lost on me.)
Enjoy, but be careful!
