At this point, I'm fairly sure he either has a cyclic mental illness causing him to be reckless in waves; is incredibly sleep-deprived to the point of executive function broadly going sideways; or has a serious problem with tweeting (and apparently earnings calls) while on stuff.

It's possibly all three.

Whatever the case, it resembles a lot what my ADHD did when it was completely unmanaged and at peak. But I didn't have a few billion dollars to make people have to put up with me. It definitely smells like impulse control/executive function in some way or the other.
