And then after another 6 doubling periods it'd get to 10%, will it? Exponential till it's not isn't exponential, it's logistic.

I had to look up "logistic" in that context.

Almost anything that is described as "exponential" isn't really exponential, if the curve is describing a real-world quantity. Real-world quantities tend to be subject to limits.

I'm an annoying pedant regarding the word "exponential", which is commonly used (especially by journalists) simply to mean "grows fast". I think it's fair to call a curve "exponential" if the relevant part of the curve approximates to exponential.

It's odd to say you're a pedant about "exponential" when you don't know what a logistic curve is!
