Elon will run it into the ground, and find some sucker to come bail him out. If it goes like other ventures, he might even find some way for the US taxpayer to fund his failures.
I would never put it past him, for now I think the one thing he could do is dump more Tesla stonk to keep Txitter afloat a little longer, but does he have the appetite for it? It's not like he can go refinance that current debt book with much better terms to buy some time
