It’s a markup language(ish) but it’s not a programming language. XML would be closer to programming, IMHO, since you could have simple things like recursion. That example is even pushing what I would consider “programming”, but anyone can feel free to disagree.
SQL is in the same category for me. It’s a query language and can get super complex, perform some basic logic, but you can’t exactly write “snake” in it. Sure, you could use cmdshell or something else to do something more complex, but that would no longer be SQL.
My simplistic expectation of an actual programming language would be that you can automate an entire platform at the OS level (or lower) instead of automating functions contained within a service or application. (JVMs and other languages that are “containerized” are weird outliers, by my definition.)
I am not trying to step on anyone’s toes here. I just never have really thought about what I personally consider a programming language to be.
It is their fault, but most of the assets listed do not amount to much. There was one that broke a billion, but that was for a gas processing facility and not something you can move easily.
I speculate that most of those assets were written off already and it’s mainly just a puff piece of an article.
