I've been thinking more about this AI stuff in terms of industry impact. What I think will happen is that upward mobility will stall for a lot of devs (no more promotions), and there will be no new devs coming in.
Part of improving yourself is knowing that, one day, you'll likely pass your knowledge, responsibility, and more on to another person so you can pursue new and different challenges.
You'll essentially see folks stuck on a treadmill going nowhere until they fall off.
