Doing things by hand is part of the learning process. Sure, you can prompt an AI to one-shot a 3D open world game, but you'll learn nothing about programming, computer graphics, or game design. That domain knowledge makes you more effective with the AI tools when you choose to use them. What you're saying might apply to experienced engineers, but not a high school kid learning the craft for the first time.

And yes, there will be people who have no interest in learning and just want to manage the AI to do everything for them. I remain skeptical that (manager + AI) will beat (domain expert + AI). It's possible that the relevant kinds of expertise will evolve, but I'm betting on some form of expertise remaining relevant for a long time.
