I'm pretty sure he means "can make great things happen" trumps "7 years Java experience on the resume"
x years experience doesn't mean much if it's the same year x times
Probably true for x < 3 and often true for x < 7.On the other hand, a person still using the same coding skills they had in 1981 probably writes damn tight efficient code...or is a God of COBOL .
Hope you don't mind the attribution "a wise man once said [...]"
maybe "a stupid thief once said [...]"
