anecdotally most older developers actually do keep up to date with the latest best practices.
As an old guy I would find it very hard to keep up to date with the "latest best practices" because I tend to think of "latest" and "best practices" as antithetical. JQuery is a good example: I never invested time in it since I figured it would pass. I could smell it from the way kids were raving about it. So this type of article foreshadowing its demise is nice to see. Like when you drag your feet on some looming deadline at work and some force majeure makes it completely irrelevant.
IMHO there was definitely a period when jQuery solved a whole host of problems for you and allowed you to write client side code much faster. If you weren't using jQuery or an equivalent you were kneecapping yourself unnecessarily.
