Is NASA really full of the best and brightest?

So I am being to wonder if we really have the smartest people at NASA. For the ones who don’t know, the Space Shuttle will be decommissioned next year and “replaced” with the Ares Rockets. The Ares I will be used for crew launches and small payloads, and the Ares V will be for large payloads.

My question is why are they creating two whole new and separate rockets? During the 1960s and 1970s, the Saturn V Rocket did BOTH crew and payload launches. Why is NASA continuing with the Ares program when, with a few technological and other upgrades, they could use the Saturn V? Or why not scrape the Ares 1 and convert the Ares V to carry both crew and cargo? I have a hard time believing that using two separate rockets is more cost effective than the Space Shuttle.

I guess only time will tell with this but I hope that NASA has made the right choice for their sake because if they don’t find a way to be more cost effective I fear they will be the victim of a very big budget cutting axe.
