Yup, it makes you wonder what's is the XML of right now. Humans like to participate in social manias, and our time is no exception.

I conjectured that it's Kubernetes. Just like XML, Kubernetes solves a problem, but it doesn't solve EVERY problem.

A sibling comment wrote that there was a startup whose mission was "do something with XML", and then they got acquired and didn't amount to much.

There's lots of that around Kubernetes now. Kubernetes companies get acquired and don't end up doing very much.

There's also another comment on the front page now (don't want to draw attention to it) where a person feels he is incompetent because he can't understand Kubernetes. It might be that he's competent, but an industry mania selected an inappropriate solution for his problem.
