While I can see your point I also think it is not directly relevant to OP. Firstly, I don't think OP meant that people are idiots for using LLM's, it was just a way of saying that skill is no longer required so even idiots can do it whereas it used to be something that required high skill.
As for the comparisons - some are partly comparable to the current situation, but there's some differences as well. Sure books and online content enabled others to join, thereby reducing the "moat" for those who built careers on esoteric knowledge. But it didn't make things _that_ easy - it still required years of invested time to become a good developer. Also, it happened very gradually and while the developer pie was growing, and the range of tech growing, so developers who kept on top of technology (like OP did) could still be valuable. Of course, no one knows fully how it will play out this time around; maybe the pie will get even bigger, maybe there's still room for lots of developers and the only difference is that the tedious work is done. Sure, then it is comparable. But let's be honest, this has a very real chance of being different (humans inventing AI surely is something special!) and could result in skill-sets collapsing in value at record time. And perhaps worse, without opening new doors. Sure, new types of jobs may appear but they may be so different that they are essentially completely different careers. It is not like in the past you just needed to learn a new programming language.
