If he's savvy he can turn this into a launchpad for his career. One of the hardest parts of moving up the chain is getting noticed by the right people. He's been noticed more than anyone could ever reasonably expect. If he's as talented as I've heard he should have no problem using that to his advantage.
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.

Anyone who hasn't fucked up at least that badly hasn't been trying.
Be honest with yourself. There's no high ground to be taken when it comes to being a perfect employee.
