Exponential growth generally means that the time between each order of magnitude is roughly the same.

At the risk of pedantry, is that true? Something that doubles annually sure seems like exponential growth to me, but the orders of magnitude are not at all the same rate. Orders of magnitude are a base-10 construct but IMO exponents don’t have to be 10.

EDIT: holy crap I just discovered a commonly known thing about exponents and log. Leaving comment here but it is wrong, or at least naive.
