I actually found myself disagreeing with that. There are many great ideas that were killed by corporate bureaucracies before they had a chance of being shipped.
I guess we just interpret it differently. I don't ascribe "greatness" to merely ideas or potential. Execution or application has to follow.
A great idea killed by a BigCo bureaucracy is like a talented athlete who is injured before his/her pro career even starts. All the talent in the world will never put such a person in the record books or hall of fame.
