>As we know, with exponential curves, they start slow and they get very fast at some point. But when is that point? The question is, where does that kink in the curve happen?<p>There is <i>no kink</i> in an exponential curve, if you think there is, obviously you don't understand exponentials.<p>In the real world, there are S curves, when the finite limits interact and overpower the exponential... those are the ones that determine who makes large amounts of money, and who doesn't. You need to time your ride along the curve such that your organization is firmly on top at that time, the use the resources gained to maintain a monopoly, and thus <i>real</i> profit.<p>(The one thing Econ 101 firmly implanted in my brain is that <i>the only way</i> to make sustainable profits in a free market is to build and defend a monopoly, otherwise you're always struggling to keep up with competitors)<p>Otherwise the only other thing I learned is that there is an organization of venture capitalists called NfX who have some strange ideas to peddle, and sounds like a cult.
