Since his cuts Twitter seems like it would be worth a lot less than he paid for it. And twitter shipped before him.
Just in the last one year, we've gotten: Twitter Notes, long form video, checkmarks for everyone, subscriptions for creators, edit tweets, see # of replies and likes on a tweet
Yes, Twitter is worth less than he paid for it. He's partially responsible, he's been too erratic. But I'm optimistic with this shipping velocity, in a couple years the company will be worth much more.
Subscriptions was released in 2021 then called Super Follows.
Notes was rolled out in Jun 2022, before the acquisition.
Basically, half the things you attribute to Musk are the major features they released before him.
