I'm sure he'll succeed in building it. The game industry manages it, for example. You can abuse and burn out engineers if that's what you really want.
That said, I wouldn't say abused engineers are particularly more productive. He can work them 9/9/6 while he's at it, I don't think that'll help Twitter succeed.
There's some very interesting things to solve and achieve at a platform like Twitter but I doubt very many people have had them as life long targets for themselves to achieve.
Twitter allows hot takes and racism, not exactly comparable.
Although he's often held up as a paragon of free market capitalism, it looks like a lot of his business ventures are actually the result of crony capitalism.
But damn that's a lot of money to burn just to chase frogs away.
Twitter's now second largest investor and likely cash backer of Elon's shares is Saudi Prince Alwaleed bin Talal bin Abdulaziz. Twitter was a huge enabler of the Arab Spring and leaders of oppressive regimes around the world would love to see it shuttered.
If your conspiracy theory has motive truth, it's more likely Saudis want what china has in TikTok or others: the ability to monitor it.
Unfortunately, just like the other far right clones, this plan only works if it's popular.
I don't buy this as he's doing it in a way that makes him look like an incompetent fool.
