Prediction: Brain drain at Twitter begins as Elon starts enacting unpopular policies. Valuation tanks. Morale becomes non-existent and Twitter slowly starts to fade from existence while competitors begin to fill the void. I give it 3-5 years before it's gone full husk.
the one thing I'm almost certain of is twitter will have better margins under musk.
It may not be worth the $44b though, he's starting at a $20b defecit.
