His "choices on what to focus on" are at best extremely vague and at worst extremely wrong - when he insisted the Tesla Roadster be made out of carbon fibre, resulting in the car costing over $100k, that was the wrong thing to focus on. When he focused on "let's bore small underground tunnels for cars", that was still wrong. When he decided "let's build electric cars" (and then bought a preexisting electric car company, whose starters presumably were also focused on electric cars), that isn't all that impressive.

So in case it wasn't clear: I'm calling Musk a celebrity figurehead, whose personal talent is fully displayed in his management of X.com.
