I feel like he's pulled his experience from "emerging technology" companies (which he's no doubt been successful), and trying to apply it to Twitter. I don't think it'll work (Twitter is an established company in a competitive environment, advertising), but it'd be crazy in 24 months if Twitter was more profitable than ever and was in line to become America's everything app.

I still haven’t made up my mind about musk. He seems truely « high tech » driven, but i’m still unsure whether he’s not mostly about marketing ( aka: whether most of his strength isn’t just to leverage the elon musk brand ).

Has anyone here worked with him and can give any feedback about his true technical or management skills ?

Andrej Karpathy (ex-Tesla head of AI) talked about this recently. "I think Elon is a very efficient warrior in the fight against entropy in organizations". https://www.youtube.com/watch?v=mbxladysbTE

John Carmack, "Elon is definitely an engineer. He is deeply involved with technical decisions at spacex and Tesla. He doesn’t write code or do CAD today, but he is perfectly capable of doing so."
