Social media should increase your number of friends in real life, but that's not been my experience. There's a lot of lonely people out there, so many somebody will figure this out.
You can't fail at "A Short Hike" or "Goose Game". Games without losing are great for young players like 5-year olds, who get frustrated when they can't time that jump just right.
afaik, that's by design. It's more like BBS'ing where people in the know can find a cool place to hangout that's not overrun by the rest of the planet. Like a beach without annoying tourists.
Weirdly, people don't have as many friends as they used to. That's why TikTok beat Facebook. Facebook is useless if you don't have a friend-graph IRL, like a telephone system with only one telephone. I think the future of social is going to be 1-on-1 interactions, everything else just becomes rep-farming, crowd-pleasing, performance art, trolling, etc.
Who even uses 3D spaces besides gaming? User-generated content is usually terrible, like Mario-maker -- most user-gen levels aren't any fun.
Anyway, go play SecondLife for awhile before you spend too many more cycles thinking about this.
The reward for finishing your work is usually more work. You need to set some boundaries/not "always be on-call" for issues. If you are always on-call your nervous-system can never relax because every phone call is a threat to normal recovery.
I always hear about selling data. What is all this data worth? If I had an etsy shop or a chess site, do companies want to buy this data? and for how much and for what? Credit-score modelling?
When advances in technology creates new opportunities, the first one to conquer the market is remembered. Everyone had the idea for a 3D shooter back in the day, but Carmack is the one that is remembered.
Daniel Rensch is my favorite, he analyzed AlphaZero games. Chess Giant is good for openings. There's a lot of good options. Learn the pirc defense for when you play black.
