There is most likely some kind of division here where 5% here is working with the best tools on the biggest problems, 60% are working with old and non optimal tools on crud making money, 15% is working with the latest and coolest at a well funded startup and the rest is just following hypes making peanuts trying to fill their resume. Here best & brightest depends on your definition; if you are in it for the money and do not live in the valley, I think brightest might be java or c# if you want to make money.
