Projecting exponential growth indefinitely is a common hazard of speculating.

If you looked at movie theaters in the 1930s, or televisions in the 1950s, or gaming consoles in the early 1990s, you also have an exponential curve

If you looked at the speed of travel in the 1970s, not only would you have an exponential curve, but you’d be anticipating supersonic flight as a regular commercial service. Which simply came and went.

And last, there are times when exponential growth does not have exponential effects.

Simply pointing to an exponential curve, especially for technology, does not answer questions. It asks them.
