You might not give him credit even if he did. We're in a thread where people are wondering whether he's not just a figurehead for SpaceX, so... what exactly are we taking about?

AFAIK Musk's involvement in Tesla was specifically to address climate change/ help move the industry towards electric cars. To the extent that this, plus improved battery tech, ends up reducing our oil dependency and eventually contributes to "solving climate change" - would you credit any of that back to him? Or just say that he didn't single-handedly solve climate change, so it doesn't count?
