I would not be an internet creature if I didn't waste years on useless internet noise.
Doomscrolling
It was a long road: VK → Pikabu → DTF → Reddit → Habr and probably something else in between I don't remember and care about. I have not fully recovered, I still ocassionally check Habr because sometimes it contains significant news and discussions related to my professional area (probably like 3% of all the articles here), even if I don't read the articles themselves: I always go immediately to the comments section to read opinions by random but at least more likely real people instead of controversial/false/clickbait/LLM-generated authors' essays.
Even if I read something useful I forget it in an hour, so it is really a non-productive way to fill my head. That is why I think doomscrolling is the worst thing I invest my lifetime on (the only good point is that I do it less and less each year).
Youtube
Oh crap, it started from watching a single walkthrough video because I didn't know where to go in some game level more than a decade ago, it ended up poisoning my gaming experience (it is more entertaining to watch someone else playing games than to play the games yourself SINCE IT TAKES EFFORT TO ACTUALLY PLAY SOMETHING) and taking the place of having actual hobbies for years.
The fact that I switched the gaming topic to PCs/technologies discussions, car blogs, life/games/etc video essays does not matter since any internet news break becomes outdated and forgotten by everyone the day after you watch a video about it. Actually I would be lying if I said that all the videos I've watched over the past several years didn't give me anything useful because I get to hear other people's thoughts on some topics and realize points of view I didn't even know existed. But in the end who cares about internet opinions when no one around you is even aware of something you think about? For example, privacy: because of the internet I learned how dangerous it can be, how I should be restrictive about software I use, etc etc. But then I wondered how does that really matter since most people live their lives as they are and don't even think about this? Am I overthinking some things I should not be? Might some discussion topics be completely irrelevant to me? "Booo, the new NVIDIA cards generation is even worse than the previous one" — do I really need to even think about getting a new GPU? Should I really care about recent AI/Hardware/Gaming/etc industry dramas? Do they actually apply to me?
I could share some links to channels I watch sometimes for the sake of entertainment and maybe information with questionable usefulness, but I think you should not pay attention: better go watch any top 100 best movie from any website rating list, at least it's memorable and you can talk about it with other people because it wasn't forgotten a few days after it was released.
