Crowdfunding will replace venture capital, and investing itself to a large extent. You don't need investment, you make the case to customers directly and they prepay you.
Crowdfunding replaces the money piece. The other bits are knowledge which the startup might need to purchase separately. Whether that will be more or less efficient than purchasing them together for startups that need both is, perhaps, unclear, but at least some startups will really only need the money (which, obviously, won't necessarily be the same ones that think they only need the money, but that's life.)
