If agents get so good that they overcome these obstacles then most mid tier companies dev staff is going to be a couple of people making sure the agents are online and running.
Vibe coding is just the canary in the coal mine.
I do agree that worse but cheap will be used a lot right now. But we also have it already with outsourcing, and not everything is outsourced.
Signaling theory provides a useful perspective here. If everyone has access to the same tools for thought, then everyone can arrive at the same output independent (mostly) of skill. That means the value of any one computer generated output will crash towards an average minimum. Society will notice and reward the output that is substantially better and different, because it shows that someone has something far better than the rest of access to or are capable of doing. This is even more heightened when the markets are flooded with AI slop. It’ll become obvious and distasteful.
Those with skills and ability to differentiate will continue their existing ascent.
My point is that the same people predicting those improvements are also predicting that LLMs will soon lead to super human AGIs.
But if it does happen, I'd rather be the one with enough technical skills to be able to jump in when agents aren't good enough or create new ones than the one managing them.
