Think of it this way, who needs engineering managers, project managers, scrum masters,etc.. if they're employable then surely actual devs that can tell what good architecture is vs bad, good code vs potentially bug code is are also employable.
But the number of devs needed, that demand will obviously decline dramatically. At the same time though, there are other careers that require programming and software dev as part of your skill set. Simply integrating LLM-enabled solutions into real world workflows is a new area that's very young and immature.
Let's not act like we're suddenly in some sort of post-scarcity utopia where all problems are solved by LLMs, where tech can solve problems, there is demand for those who can use technology to do so. However, I see a lot of people attacking the technology and resisting change a lot, and to those I suggest they look up every single technological revolution and see about the fate of such people.
