My experience so far tells me that the default path with AI tooling is that it lets us create without learning. So the author is right in that they can pay for a seat in this revolution whenever they want.

A practitioner with more experience maybe a few percentage points more productive, but the median - grab subscription, get tool, prompt, will be mostly good enough.

I think this is true at the solo developer scale, but I suspect experience will be much more evident when working with a team.
