1. Successful ones who have to be convinced that they should risk their reputation and take on the headaches at Uber.
2. Less successful ones, where you have to convince the current Uber decision makers to give them a shot.
I think the field is narrower than this article suggests.
the ones from category one might have difficulty knowing what to do - unless we're talking about the lyft CEO they know success from something other than uber. that might not necessarily be good.
the ones from category two might have the same trouble as one, but add to that that they will have to compete/convince the board of probably every little move.
and if they don't do something fairly dramatic, fairly quickly, the good people at the mid and lower levels will start to flee for greener pastures.
