I guess this was *technically* correct at the time, but I distinctly remember thinking that this was a stupid prediction even back then, which was pretty much public opinion at that time IIRC.
So not really any better in my book
You can't really make that kind of prediction with anything with exponential growth.
What looks small at first can blow up quickly (which is the whole point of exponential).
You can't predict the outcome of a 1000 mile trip by the first mile (which is what Elon did).
