It |> won't be forever, so let's get ahead of it. To boost this point, exponential growth, approaching infinity, becomes asymptotic. There is no way that is going to happen and there is no way we can do anything about it if it does. For one thing, there is a finite number of people on the planet. There is also a finite number of nodes we can build in a year. Both factors create upper bounds for the problem under discussion. What *can* happen is a classic "S" curve that has a rather steep cliff at the front of it. But, that is like the six blind dudes and the elephant. The cliff isn't the whole curve. Sooner or later, you run out of atmosphere and you can't climb anymore.
