I'd correct you, slightly: Kalanick's brohaviour (as you put it) has quite a lot to do with stock market success because aggressive, amoral, bro-like investors collectively act like economic success is a matter of showing personality traits like their own. So, if economic success ONLY depends on eliciting investment from these people, then you need to be dominant and brutal in every perceivable way, including sexual harassment, to signal that you're successful. This is far from new. If success also involves building a functioning company, you've got to look beyond investor bros as a metric, and this is where Uber hasn't shown quality.
