I wouldn't bet against Elon. Obviously he's invested a lot of $$ but i can assure you he's looked at the #s and sees a strong play. May take time but doesn't look like he's wasting any in getting right down to it. I'd look for Twitter to be moved out of California in the near future to a more tax friendly state with a better workforce than California can offer. Once lean, mean, and profitably humming along Elon will sell it for a tidy profit.
