By now, you've all seen The Programmer's Dress Code.
No (or very few) devs look like this at Microsoft, for some reason. It is not that we hire people on looks. We need everybody - dev, test and PM - to be good communicators. And, probably, if you have zero dress sense (or bizarre facial hair), you won't be too good at the communicating part.
But I'd like to think we have developers as good as Bjarne and the others. Some of our dev architects certainly think they are.
