The elite gurus will get paid handsomely, while promptgrammers will be paid less since they've become a less-skilled commodity, and the company has to pay for the expensive tokens they'll avidly consume.
I've seen someone jump from Wordpress to deploying internet-facing APIs because 'they have PHP experience', and the holes in their knowledge were filled blindly by an LLM. I have also argued with a seasoned developer about how their code didn't need linting because LLMs 'already follow best practices'.
The future doesn't look bright when LLMs allow future generations to feign required knowledge.
I don't see a reason why expert humans will remain more expert than AIs.
But really, not everything needs to be maximally efficient and perfect. Human to human interaction is important for its own sake.
Ultimately it will probably come down to liability, though. If someone receives the wrong dose of a drug due to a software error, whose fault is it? If you want it to be my fault, then I'll want to understand the software. Loads of people would take on the liability without fully understanding it, though. The future doesn't look good, but we'll just have to wait and see.
