When we talk about an artist being overrated, we're talking about whether their works are deserving of the reverence, praise, and patronage that they attract. Its largely subjective — built on interpretation, comparison, retrospection, etc.
Elon Musk is a truly proficient capitalist. Great at creating capital. So, in that sense, no he is not overrated. There is nothing really subjective about capital — you either have it or you don't. And despite all the warning signals, people still heavily invest in his ventures.
But is he overrated as a leader, as a visionary, as a genius — the subjective measures. I'd argue, yes. Doesn't take a genius to create capital. As he's done nothing artistic or altruistic for us to debate the merits of his life, I can't imagine what other criteria he can be evaluated upon.
