Opinion sure, but some are more probable than others, and valuable in predicting the future and allocating resources accordingly.
The most used language on stackoverflow is Javascript, does not tell you anything about trends?
Javascript is no longer the hack you are thinking of with ES6. ES6 is world class and I find it hard to fathom 19 year olds in SV building desktop applications using Java Swing & FX (which supposedly some old timer HN claim is happening which is a lie because it's way more time consuming, I've built with Java Swing and Electron and people commenting have no fucking clue the night and day difference) vs Node.js + Frontend framework of some sort. Walmart also adopted Node.js fairly quickly which sort of kills the argument that Java is king. In fact, less code is a trend in the enterprise with the rise of Scala and other less verbose languages that run on top of JVM.
Javascript has evolved from it's humble roots in the browser, it is now expanding and finding developer mindshare well beyond the browser (in case you didn't know about Node.js).
I find it hard to continue this discussion when it's clear you haven't spent any time recently with Javascript and instead relying on your outdated misconceptions about Javascript.
Please spend some time with the modern javascript tech stack before you offer a rebuttal so you are using the latest facts.
