I think the whole "AI will replace developers" thing makes sense to people in silos.

I want to do X I can ask AI to help me with X.

But the thing is that as businesses grow and scale one person cannot even keep in their head all the things that have to get done, let alone write it in such a specific way to get an AI to accomplish it.

Even Jr developers (if used correctly) are not just code assistants, they can actually take your mental load away as they grow and then provide projects / ideas that you didn't even originate.

People have mental limits to how much they context they can keep in their head at the same time, AI does not magically solve this fact.

Hire and develop talent, share the load.
