Collapsing companies can be an excellent way to jump several rungs on the career ladder at a time.

If you're an ambitious Level 2 Hierarch and you know your Level 3 and 4 Hierarchs along with many of your fellow Level 2s have just departed, you can roll the dice and maybe become a Level 4 Hierarch before you depart in 6 months time. Experience allowing you to become a Level 4 Hierarch at a company that isn't collapsing.

Of course, it isn't clear that Musk is looking to promote any Hierarchs, so this would be a gamble.
