One of my clients is a relatively major educational institution and they still use ColdFusion to drive some in-house CMS abomination. If it ain't broke?
I do still use Dreamweaver templates sometimes though! The awesome static site generator of the 90s. You can give the templates to marketing folks and they can use the GUI to make content updates.
(I know I should feel bad for not using some JS framework that nerfs their SEO and breaks the back button.)
12 years experience in Vue or Backbone? Coldfusion was forgotten in a Flash, sorry for the pun. I do like jQuery, paired with it Coldfusion in the article, because of it's simplicity over what seems heavy React, Angular, and expect it to outlive them. I also expect human readable CSS to return, and for PHP to live a long life.
As a former CF dev I laughed out loud when I saw that part - CF+JQuery. But yeah, it's amazingly resilient. The Java bytecode was quite fast and stable.
However there are certainly better tech stacks available. For one, the variable scoping was nightmare-inducing stuff.
There was actually a post a few weeks ago about a project which is essentially a modern CF runtime, while I still can't imagine anyone using it to build new projects, I'm sure many orgs are still actively using it to glue their legacy systems to newer ones
