The reason we aren't just a slightly odd species of chimpanzees is that we developed the ability execute on ideas. Otherwise we're low-hair primates thinking about maybe fire.
I'm not arguing that execution has no value. Obviously ideas, particularly business/startup ideas, must be acted on effectively in order to become real. But: ideas are logically prior to execution; the ability to conceive of abstract ideas is a far larger developmental step than is the subsequent ability to act on those ideas; and being able to have abstract ideas is the thing that most definitively separates homo sapiens from all other species on Earth.
