I wonder why exponentials are so common in nature/physics but tetration is not

[isaac21259]

Exponentials come up quite naturally from differential equations because it's often suprisingly useful to talk about something's rate of change in terms of itself. As far as I know there's no similar connection with tetration.

In other words: if it grows or decays by a rate that's proportional to the current amount, over time it'll follow an exponential curve.

The numbers get impossibly big almost immediately.
