IMHO this analogy doesn't really click, on multiple levels. Any old timer who uses jQuery surely is also aware of querySelectorAll and friends. There's even an entire website dedicated to catering to exactly that transition[0]. I don't think anyone defending jQuery is doing so out of a sense of hubris towards outdated knowledge, but rather because it ironically is more lightweight than a lot of the modern SPA craze, while still being more ergonomic than vanilla JS.

To try to shoehorn this back into the compiler analogy, modern frameworks would be like the advanced, complex and opaque compiler, and the grey beard is the guy that understands how stuff like HTML streaming and font download prioritization and hidden classes affect performance, whereas the team lead is analogous to the run-of-the-mill bootcamp grad that knows how to use the framework-du-jour but is way out of their depth if venturing outside the comfort of the framework and into the depths of those advanced topics.

And I think the gov.uk use case here might actually be an outlier in the sense that it actually considers performance of an already tight codebase, whereas a lot of jQuery deprecation efforts bring with them heavier alternatives in the name of maintainability or developer productivity or hiring or whatever. To be clear, many of these concerns are quite valid, but it seems a bit disingenuous to create a false dichotomy between understanding of low level concerns vs concerns about SDLC management. They aren't mutually exclusive.

I think you're trying to draw too much of an analogy here. The point is just that advertising jQuery expertise on your resume today is evidence (though not especially strong evidence) that you might be someone whose skills are of diminishing relevance. Myself, I'm not convinced there's much harm in using jQuery, it's not exactly heavyweight. But if in fact fewer and fewer pages include it, then your expertise is relevant on fewer and fewer pages. It doesn't make sense to add a dependency on jQuery to satisfy a single dev's preference.

If your expertise is in low-level browser performance but you lack deep knowledge of React/etc, your skills aren't of diminishing relevance, and probably won't be for a long time.

I am not sure that the story has anything to do with the situation of jQuery today, because as I can see in your story there was a guy whose skills were of diminishing relevance, but surrounded by people whose skills in that area were never a thing in the first place, what I can draw from your story is that it's useless to cultivate an expertise in a niche field because it will be irrelevant in a few years?

I don't think you're really listening

IME, people list jQuery in their resumes all the time, typically as part of some previous job many eons ago. But I have read hundreds of resumes and just don't see people advertising jQuery as a primary skillset anymore, so to me suggesting that people still do this sounds very close to a strawman.

Something like Angular.js is a more apt example of a skill people still do advertise as a primary thing in their resumes these days and it most definitely plays into the diminishing relevance thing. On the other side of the spectrum, you have newbies writing down "HTML/CSS/Javascript" in their resume, which basically screams zero experience (aka "low/no relevance until they learn to speak the cool framework lingo"). There are plenty of other quote and quote "uncool" skills in actual resumes. Flux. Sagas. Ember. Etc.

So, yes, an argument can certainly be made that recruiters/interviewers do "discriminate" against various stereotypes to various degrees, and it isn't necessarily always based on ageism. A recruiter that reached out to me recently had an interesting term to describe this phenomenon: "skill commoditization", aka looking at people as snapshots in time, and evaluating some skillsets to be intrinsically worth less than others, even if they have some amount of overlap, instead of looking at people as malleable entities. It's worth thinking about how treating developers as commodities might hurt your hiring, especially if your hiring revolves heavily around evaluating for expertise in a specific framework.

Thank you. That needed said.
