What’s the point of posting a thesis if you’re going to immediately argue against it? I haven’t seen anyone really arguing that capitalism favors intelligence, at least not in the sense you’re arguing against. Capitalism favors efficiency, or rather it favors nothing, it’s just that with relatively unconstrained conditions for competition those who are more efficient tend to survive. You clearly have an axe to grind against Musk, so why not post an opening statement against that guy in particular, instead of what is effectively a strawman against capitalism as a whole.
