I don't think I buy that bombastic of a statement
50% employee would cripple Twitter instantly, I honestly don't think any big institution worth 44bn can afford to lose 50% workforce on a whim just like that. Shits are bound to hits the fan.
Regardless of how inefficient Twitter before Elon, I don't believe they're employing 50% more than they need to
From what I've heard, it honestly sounds like Twitter could lose 50% of their engineers and not blink. Twitter is very nearly identical to what it was when it came out, and it's been paying loads of engineers for years and years and nothing new ever comes out of it. Who knows what they're doing in there.
