The dangerous bit is that an exponential curve will also be a fairly good fit for a logistic function that's not yet fully observed.

Every apparent exponential in the real universe must actually be a logistic or some other bounded curve.

Except for the size of the Hubble volume /s

Cosmic inflation should guarantee an exponentially growing observable universe.

Otherwise, we would have about a hundred trillion people infected with Covid by now.

Yes, and the one thing you expect on a logistic function is arguments about whether it's linear or exponential.

But with the amount of noise in economical data, I don't think is evidence of anything.
