Yeah, great point. With so many bright minds out there, and the technology knowledge threshold becoming so much lower, it seems that all bases have been covered a few times. But, there are many examples of companies that were not first, but who have become dominant. Reminds me of a story I heard of two economists walking down the street. They spot a $100 bill lying on the ground, and one says to the other "Hey, a $100 bill. Should we grab it?" And the other says "Nah, it must be a fake. If it was real, someone would have picked it up already." *edit for clarity
