The way I see it all these supposed "inefficiencies" got twitter a valuation of 44B and a hub for people across the spectrum to congregate. Firing all these people and goining hardcore mode has only slashed the value of the company by 80% and even more of a cesspool of bots and misinformation, not to mention the exodus of advertisers and a large portion of users.
This is a good example of moving the goals posts. There were lot of claims that [A] would happen. In the end, [A] didn't happen. People say, "maybe it's time to admit that the claims that [A] would happen were wrong," and the reply is "no, [B] happened, so it doesn't matter."
It's certainly possible to argue that Musk hasn't done a good job of running Twitter. But the claim - made by many people here - that the site wouldn't remain function after 80% of the staff was laid off certainly proved to be incorrect.
So yeah. Good job.
