Shouldn't a bad job market convince people to get a degree?

You only miss a bad job market entry and low salaries, you need every meagre advantage you can get.

100% agree on a degree being a strong signal, by the way.

If we're speaking realistically and not idealistically, then the primary point of a degree is as an investment in a job market. You go deep in debt with the aim of getting many times what you invest in return. But in the case of a bad job market, you're investing serious money (especially in modern times) for what may not ultimately pay off. And even if LLMs don't reach their viable potential, they're still likely going to significantly depress wages/employment for many forms of knowledge work, making a degree even less valuable.

I went to a top 10 university, but won't be encouraging my children to go to university at all, nor will I strongly discourage them. But I will make it clear that it is a choice with pros and cons, and in modern times I personally think that the cons outweigh the pros. Of course if they want to do some form of engineering then it will probably be necessary, but there's lots of wild careers like underwater welding that make big $$$, are fun/physical, highly skilled, and you get paid to learn instead of going 6 figures in debt before you even enter the job market. And it's something that will always be needed, everywhere, and isn't going anywhere.

And the reality of life is, like the article says - where you start is not where you end. Once you get your foot in the door pretty much anywhere, your formal title often quickly becomes much less relevant than the skills you have.

Maybe, but the degree has to be paid for, with time and money.

Not if the baseline assumption is that the value of a degree continues to go down and you could've climbed the ranks of plumbing instead of getting a white collar degree.
