Spoiler: He is not. But he is very good at faking it.
Anytime he tries to give a serious opinion on anything related to computers: It is laughably bad and out of touch (SQL, compilers, languages, performance, etc... ).
He definitively has a scientific background but definitively not "Tech" as far as computer are concerned.
To be honest, I’m actually interested in this hypothesis: is he legitimately skilled/knowledgeable, or is he indeed faking it? And for either side I would like to see evidence. This question is interesting to me because some of his companies have made substantial contributions to pushing the frontier of technology (reusable landing, high launch cadence, electric cars, energy).
If he is really faking it, that might even be good, because the success of his companies might be replicable and could continue without him. But what if he is not?
On a domain side to nerdery: video games. There is zero doubt he is faking it entirely.
The streams he publishes on game like PoE or Elden Ring, have been long commented on online boards

And honestly, I can understand it entirely.
He has a public image of "geek/need hero" that is honestly inspiring. And that benefits him a lot because it bring people to trust his decisions. He has all the interest of the world to maintain this image.
People he hired for these companies made contributions.
Martin Eberhard was the technical co-founder of Tesla and Elon Musk is trying his best to erase his contributions to Tesla.
Eberhard wasn't that technical and was the CEO in the early years.
But that has nothing to do with the valley chips and computer nerdery
I think it's fair to say he at least was a nerd. He was a dweeb getting beaten up in school, burying himself in books and computers at home. His skills are doubtlessly outdated now, but does that really mean much? Woz's skills (which to be perfectly clear, outclassed Musk's by miles) are doubtlessly out of date now too, but nobody would say Woz isn't a nerd.
I think the part where he grew into an unstable dirtbag might be influencing the way people see him now. Saying that is is, or at least was, a genuine nerd shouldn't be seen as any sort of excuse for his scamming, lying, etc.
I do believe he read a lot of sci-fi in his youth, if only because that would fit the pattern of a young boy who doesn't get along well with their peers and turns towards solitary pursuits like computer programming. He seems exactly the sort to have read lots of Heinlein.
