So Elon paid $44B for a company now with 900-odd employees. For a 10-year ROI, that's $4.4B per year profit, or $440 million/per employee
For contrast, Netflix has the highest revenue per employee at $2.63 million/person, and Apple is second at $2.38 million, and Alphabet & Meta next at $1.64, and eBay at $0.9 million per employee.
So, he'll need to get 200x the profitability per employee, just to get a total profit equal to his investment in 10 years.
To get a company valuation back to his purchase price, at a 20X multiple, he needs to make those employees as profitable per employee as Apple. In a business that has never been consistently profitable, has not much of a moat, and in which he'd panicked almost all of his advertisers, the primary customers.
Good luck with that
