In some senses, yes.
I’d probably say that it’s more a matter of having or having had a better engineering crew (which includes Musk as a component). With a better crew, you have more options. With more options, you have a larger set of cost/benefit selections that you can make, so you’re better positioned to get the best one.
But, Julius Caesar is the person who grew the Roman Empire to its maximum state, and also the person who began its collapse by thinking short term and egotistically rather than long-term and selflessly. Tesla invented alternating electricity and much of our power generation infrastructure, just to morph into a penniless crazy man. Howard Hughes created some of the cleverest aircraft of his day and one of the most successful Hollywood production companies, then became obsessed with building an all-wood airplane that had no value, then became obsessed with collecting fingernails, hair, and urine, and spent his last years hiding in dark rooms, in the middle of his compound.
Smart, capable people aren’t flawless, unchanging statues of everlasting health and fortitude. The man that made Tesla and SpaceX might still be that same man. He might also be the result of taking that man, injecting him with loads of ketamine and LSD, topped with a good helping of brain-devouring syphilis from varying orgies, and destroying most of what made him great.
Saying that he did create amazing things does say that he had certain talents for - at minimum - recognizing the right moment for a technology and assembling a crew who can pull it off. But if he can’t maintain that crew - because they don’t want to work with him - then that will fall apart. And if his ability to tell when it’s the right time for a technology, and when it’s time to rein in the ambition, then he’ll end up in R&D hell and waste exorbitant amounts of capital on what are - at the end of the day - little more than advertising gimmicks, while others take over the markets that he used to lead in.
Plausibly, the guy is just blowing off steam with all his recent craziness and pivoting, politically, in order to cash in on the gullible swaths that follow Trump and throw bad money after bad. That would be a rational and reasonable decision. While not a benevolent act, it is good business and I wouldn’t fault him greatly for it.
But I’m not particularly convinced that, that’s what we’re looking at.
