What everyone has to understand, is that Elon's companies work by decree. Tesla engineers see a tweet that went out to 100m people about what they're going to deliver in two weeks and go "ohhh shit."

All of these changes are coming directly from Elon, impulsively.

Another core tenet is to remove components and try things until something breaks, and then add those components back once they've been proven to be necessary.

This is fine for a startup, but it's quite disruptive for a mature platform with 450m users.
