I thought we already had an "everything app": the web browser.
The problem with that is that you can buy stuff using it and there is no central app owner who gets a cut, and people think it's right that way! A defect that urgently needs to be fixed, can't have other people making money and poor tech companies being left out!
Removing friction must be valuable, Amazon's 1-click shopping was worth beaucoup bucks for them. Chat, Gifs and videos, news and Venmo all in one would be adopted quite well. Until all the trolls and scams pee in the pool and Musk says "freedom of your money to disappear" when snowflakes complain. And then you can be banned capriciously because the owner doesn't like you.
Raise your glasses if you wish Elon Musk's Twitter do die out.
P.s. I can't wait for Blue Sky to be released https://blueskyweb.xyz/. That'd be the point in time when Twitter's death is quickly accelerated.
