He makes a lot of promises and gets a ton of government funding and pumps up his stocks. For example; the catchable booster is cool but it was not invented by him and his promises of giving boosters a turnaround of 24hrs or something is wildly absurd. Also, the Starship HLS has been delayed repeatedly and it was promised to carry thousands of pounds into space when it has repeatedly exploded while carrying no weight. These are just a couple of things and despite the failures, he continually wriggles out of consequences whilst pumping up stocks with bullshit.
