I see your perspective, but the guy is an iPhone engineer, I don't think having lost a prototype at a bar in a very public way can possibly add anything to his resume or make him stand out more in a positive way. I could see someone maybe specifically contacting him and offering him a job after this event, though I don't really see why they'd single him out unless they were looking for an iPhone engineer specifically.

In other words it may have some net positive effect on his career, but it seems like he was probably doing okay anyway and it's at least equally as likely to lose him a job than to gain him one.
