Many of the "people don't understand Exponential functions" posts are ultimately about people not understanding logistic functions. Because most things in reality that seemingly grow exponentially will eventually, unevitably taper off at some point when the cost for continued growth gets so high, accelerated growth can't be supported anymore.

Viruses can only infect so many people for example. If the growth was truly exponential you would need infinite people for it to be truly exponential.
