Okay, that was a surprise. I get the idea that one should work on new things, that merely trying to out-compete is counter-productive (competition is a zero-sum game after all).
On the other hand, some benefits may only come when there's enough players that compete with each other. Take Virtual Reality, for instance. There's the Occulus Rift, Now Sony is working on it, there was valve… at one point, there will be enough player to make a market for low-latency, low-persistence, high-frequency, ridiculous-resolution flat panels. The smartphone industry pushed in that direction of course, but the limit of what's useful for this industry is clearly not enough for VR. Anyway, with this new market, VR will improve as a whole. Without the competition that is currently forming, I think those miraculous flat panels wouldn't come out as fast as they will. That said, those folks are still working on something new…

Now that I think of it, maybe he was talking about maximizing one's marginal impact? Like, let the Occulus people work on their Rift alone, and try and work on something different. Even if that slows the VR revolution down, we may now have two revolutions. Hmm…
