Good at what he does is knowing when to put his money where, lying and being charismatic. He had a judge ruling to make him founder of Tesla, while kicking off an actual founder. Also didn't found Paypal. His science/Ai edavours are questionable at best. Tesla according to Elon has 'better than human' self driving since 2016, but somehow Teslas nowadays still wanna run over pedestrians/overtake when it's dangerous, so yeah. Do I even need to mention the Cybertruck?? And Space Xs glorious goverment project where they got 3 billion to go to the moon by the end of 2024, which they actually did. Wait, they didn't. Oh yeah, also the guy who promised to be at the moon by 2024 said humans would be on Mars by 2021. Ah yeah and his clever new invention 'Hyperloop' (which is a concept from the 1900s). Which back then was realized not to be feasible at all, but genius innovator Elon Musk thought otherwise with his Boring company. How much do you find of the hyperloop nowadays?? Should have been the next big step for humanity according to Musk.
