Catching up is usually faster than pushing the state of the art further.

I think the smartphone industry’s slower growth is more the result of diminishing returns from the form factor than the cessation of Moore’s law.

Not so for exponential growth. e^x will always be greater than e^(x-t).

The base for an economic growth model does not need to be e and generally would not be the same for different economies. The base for catching up economies is usually higher than developed economies (say 1.2 vs 1.1).

In any case, a simple exponential equation is too simplistic for real economies.

You missed the part where they can simply borrow to catch up:

“One is that as Chinese technology converges on that of advanced countries, the room for rapid improvement through borrowing declines”
