Where do you draw the line? If going from forming sentences to achieving medal level success on IMO questions, doing extensive web research on its own and writing entire SaaS apps based on a prompt in under 10 years is just "evolutionary", then it's one heck of an evolution.
It's always been the case that people in to tech see a smooth slope rather than some sort of discontinuity, like you might perceive if you stepped back a bit. That's why you can go laugh at "thing makes a billion dollars even though nerds say it's obvious and incremental" type posts going back 25 years. iPhone is a great one.
