How Do You Know if You're in an Intensely Crushed Space?

Pall: What was your intention when you started? Was the intention just to build another great product, or did you have a vision that was fundamentally different. And so this he question is for all the founders that are in spaces where the v cs are saying, ah, that's an intensely crowded space. Or if you make that future, what would prevent google or mikrosof, just from copying you and not listening to yourself? I think sometimes intomit of unity, when you start, you do not know how big it is.
