There's quite a few articles suggesting he doesn't quite have the engineering chops as some of his fans believe. Here's one example that shows that he consistently falls short of goals. What's really telling is that many of the goals that falls short are caused by pretty basic problems, like getting doors opening or closing correctly, or car trim pieces properly installed. There's also been a slew of issues with all of his companies lately, like deaths caused by deficiencies in Tesla's self-driving car technology, SpaceX losing a rocket on a launchpad, etc. Of course, he's only the CEO, not the guy designing these components, so we can't put all of the blame on him. But you can blame his combination of pushing certain ideas with fully vetting them and his inability to grasp basic engineering problems, as well as being really bad at managing other people, as a major driver of these failures.
Yes actually. I also know that Hyperloop is basically impossible when taking account safety and practicality issues: debunking video.
Heat shields are old technology, dating back to the 1960s. Maybe he did a good job in this one particular instance, but this is hardly a major accomplishment.
You just quoted a WSJ hit-piece as evidence that Musk hasn't reached his goals. He's accomplished more than he's hoped for. He's said multiple times he expected Tesla and SpaceX to fail. Now Tesla is making 100,000 cars a year and SpaceX is landing first stages on barges in the ocean. He's consistently achieved milestones no one ever has with his companies. You have no facts to prove otherwise.
He also describes himself as an engineer first and foremost. Many of the first engineers that worked for SpaceX described his uncanny ability to absorb information like no one else they had met before. He's a genius. Sorry if that rubs you the wrong way.
The proof is already written in stone. 8 years ago there were zero Teslas. Now there are 150,000 driving around. 3 years ago SpaceX started testing landing capable rockets. They've landed 5 first stages this year.
