Well, even if I subscribe to "every company under Elon's management is a shit show" (and I do), and I don't idolize him (I really don't), if I lived anywhere close and were in my 20s, I would consider joining for a year or two just for the lulz. Twitter is still insanely influential, so it would be fun to be behind the scenes. I also suspect that software engineers can still learn a lot there.
