Well, imagine racing car manufacturers competing on making better, faster engines. At some point engines are so strong that other parts become the limiting factors, such as tires for traction. Now someone invents superfuel, but cars are still only marginally faster because the additional engine power didn't change the bottom line much.

That's what's happening in software. We knew that coding is only a fraction of the overall work, and even completely automating it away won't increase productivity by an order of magnitude.

Yes, the job is changing, but only parts of it. High-level engineering best practices still apply even without the coding part. And there is no free lunch.
