Have we actually lost PHP and jQuery? I don't think so. I mantain some of those website, I don't I'm losing much. If I have a single dynamic page, I might actually use PHP, but if I have a complicated app, I use a framework.

If the "industry" default has new JS/Node powered ecosystem, perhaps some people, including myself, would agree that PHP frameworks are still ahead of the overly modular JS frameworks, there isn't anything like Laravel or Django for the JS world.

But, for simple cases, templates are still very common, including static site generators, but even PHP.
