That's like saying farmers that don't use pesticides will die out. There's whole industries around doing things not the way big companies say you have to. Human-centric firms will pop up and proposer.

That's just a baseless assumption. To use AI well you should do the things that allow you to use stuff well. You shouldn't just use it any way you can because you assume that 'not using it at all' is not the best option.

This is literally the same with every single technological development.

Ironically, companies overusing it will probably die at a similar speed. Maybe faster, even, depending whether cash burn or technical debt catches up to them first.
