The reason for this is: the only way to show productivity gains enabled by AI is to lay off people and pretend you are doing the same amount of work (while in reality you are severely dropping quality and accumulating technical debt).
Productivity gains can also be achieved by reducing scope. The coming issues will be that because of increased productivity (idea -> working code) that software is too bloated, does too much, that product managers will and can say "yes" to everything. Until it becomes unmanageable.
And that's not a new problem, it's what basically every programming adage / wisdom going back 70 years is about.
