I have worked in tech long enough to see some common patterns. It's usually intermediate devs (though not always) who get excited by new tech. The same people are usually pushing to use shiny new tech in places where it isn't needed. You don't get cynical old school devs trying to replace working parts of the tech stack with tech less than 5 years old.

Personally i think developer skill has far more to do with maintainability than language choice. And I have worked with a lot of shit code.
