For $17 mil you can't replace Git either. Can't get it done.

The problem is that the cost of replacing git isn't measured in money, it's measured in time.

It's one of the few programming projects that no amount of money can buy, and ironically getting more money often means having less time.

At the same time, you just can't scale up a company then decide to disruptively innovate on your core tech. You either put your nose to the grindstone or you let yourself play and explore but you can't do both at once.
