That's an unfortunate assumption. Looking back at historic examples, the Windows API was complicated to use while the NeXTSTEP API wasn't. Is there any question which was created by an "elite team"?
Part of the complexity is that it's solving like 15 major problems at the same time in an interconnected way. It's also solving them for people like google which means there are a lot of requirements for all the things it needs to do.
Because it does new things, in addition to old things in new ways, there's a steep learning curve for all of its concepts. I totally agree that doesn't mean it couldn't be more elegant and "simple," but the win32/nextstep analogy isn't fair as they were far more similar than vanadium is to anything else. Vanadium is like a hybrid of (to use existing concepts) dns/http/ssl/json/bluetooth/nosql/ntp/kerberos and more. When you put it all together there isn't a lot of existing references or cognitive frames to help you "get it" righ away.
I was looking at http://www.opengarden.com/meshkit.html but they don't seem interested in my scale.
