This is an excellent point. The analogy I like to use is based on prospecting: you can try to find fully-formed gold from the earth or you can smelt down ore into something useful. Right now the valley is full of prospectors stealing gold nuggets from each other, and I think there is a ton of opportunity to transform smart, hardworking people into great employees.

Of course this requires time and training, which some start-ups feel they can't afford. In the end I think it's worth it to focus on finding talent that can learn quickly rather than emerge from Zeus's brain fully-formed.
