I was working with an old carpenter friend of my father's last weekend, and he was telling me a story about a guy he apprenticed with. The man didn't complete 8th grade, and could barely do arithmetic, but was a master mason and carpenter. He was once tasked with taking apart a good-sized sawmill and reassembling it on another site; he spent a day walking through the existing plant, looking things over, without taking any notes, and then when the equipment was packed up and moved, set the whole mill back up at the new site from memory, with a healthy dash of experience to supplement.
EDIT, forgot the conclusion: Clearly, education isn't everything. It's at best a proxy for talent.
