This is incorrect. It’s basic economics - technology that boosts productivity results in higher salaries and more jobs.
Companies that are doing better than ever are laying people off by the shipload, not giving people raises for a job well done.
I'd say that using AI tools effectively to create software systems is in that class currently, but it isn't necessarily always going to be the case.
There are so many counter examples of this being wrong that it is not even worth bothering.
I love economics, but it is largely a field based around half truths and intellectual fraud. It is actually why it is an interesting subject to study.
