I think his final paragraph is spot on: unless you’ve somehow secured exclusivity via contract, patent, or the like, any idea worth doing will be done by many, many people. People smarter than you. People better funded than you.
If your only competative advantage is having the bright idea first, you might as well not. If your idea depends on being the big player in a zero-sum game, you might as well not.
Bright ideas are nearly worthless. Execution is everything.
You have to compete by building a better product and a better business around it. Work hard, market hard, and deliver something that is more useful to your customers. Concentrate on markets that have room for more than one solution. Don’t hope cleverness will save you.
