Yep - "hurr durr I fit a two parameter exponential to three data points OMG guys we should panic now" is just about the weakest argument that has ever been made

Yep - "hurr durr I fit a two parameter exponential to three data points OMG guys we should panic now" is just about the weakest argument that has ever been made about any of this stuff. At the very least, many of the things he's showing would be theoretically expected to follow logistic curves of some form, not pure exponentials.
