Anyone who does not do the grunt work of learning how things work at a granular level will run into trouble when their agent suggests "let's re-write the firmware!" and the user says "sure, whatever that means", the model will get stuck or break something, and there will be no one around to understand what is going on.

With strict version history that may be okay, but hopefully their agent already thought of that for them too!

Whenever you "automate away" things that are actually a part of you, you lose a part of yourself by definition.

When you automate physical movement, you atrophy. That implies ill health and helplessness/lack of resilience should your automata fail.

When you automate intellectual movement, the consequences are even more dire.

Most people lead a very immobile life already, in both aspects. They don't realize the consequences, if everybody did the same.
