> Honestly you need both. executing with no market differentiation would be difficult to grow and/or find investors. That's formally known as "begging the question", i.e. a self-referential circle that uses the argument's thesis in support of the argument. History doesn't care about marketing, it cares about ideas. We all have benefited enormously from Einstein's ideas, and those of the creators of quantum theory, but none of those people marketed their ideas, or would have considered that important. History doesn't care either. We remember (a) inventions, (b) the inventors, and finally (c) those who exploited the inventions, in that order.
