The growth curve here is more than exponential 2^n, it's 2^2^n.
Unlike the parable of getting twice as many grains of rice for each subsequent square on a chess board, this pattern also progresses twice as many squares each turn.

I am a bit confused as to what you mean. 2^2^n is still classified as an exponential function.
