They are partially reversible, but definitely not fully reversible. For example, there's no taking away that Musk started his tenure by angering advertisers. He can apologize, he can make amends, but there's no taking away that some amount of the damage will remain, if only because some companies already made new plans, allocated their budget, and aren't about to tell some other company that they changed their mind because Musk said "sorry".
> 2. If he acted responsibility, he still would be running a company that is losing billions (plus the extra debt he saddled it with) in a terrible economic climate. I don’t think he can afford it.
Well, if he couldn't afford it before making things even worse, how is that not an existential crisis?
