Angela Merkel is also not a physicist. She studied physics and then published a few papers in 'quantum chemistry' but for basically her whole adult life she's been in politics. She's as close to a professional politician as you'll find.
I know it wasn't you but Rowling and Obama are odd picks for high status individuals. Rowling is well known but is currently having her reputation blown up and being stabbed in the back by the starlets she birthed, because she's not on board with "people can pick their own gender at will". Obama was high status when he was POTUS; where is he now? Does anyone know what he's up to these days? It's not Obama himself that had high status but the position.
In my experience Musk gets a lot of respect. I know a totally non-technical financial CEO who always cites Musk as his inspiration. The guy even likes to see himself as kind of like Musk which is hilarious to me, as he is slightly more likely to be struck by lightning than sit down with a pile of textbooks to learn a new technical skill. That's just not who he is.
