His present situation with a multi-billion dollar agreement he entered based on hype and is now very desperate to exit seems to suggest his hype management skills have room for improvement.

He typically creates massive hype, well over what he could possibly deliver, not sure I've ever seen him temper hype.

Just remember the launch of Tesla auto-pilot, where he was promising full self driving within a year or two, so good that you would let your car work as a taxi while you don't need it and it would become a passive stream of income so great you would see your investment back in around a year! He actually said "our goal is to make Ilit financially irresponsible to buy any other car". This is not a man who "manages hype".
