I won't say what you're saying isn't real, but it is happening on a completely different scale than the size of the Java ecosystem. Even on the JVM, what you see as "plenty of Scala" doesn't even amount to 5% -- not that it matters, but it's just an example of why I think your view is skewed.
The size of the Go ecosystem is hardly 1% of that of the JVM (rough estimate), and while Node.js/Python are "a thing" (and are the only languages/platforms of those you mentioned that are used to a substantial amount outside of startups), they are still tiny compared to the use of the JVM. Even in Silicon Valley (which is in itself a very small portion of the software world), the large "webby" application companies (with the notable exception of Facebook) are JVM shops: Amazon, Google, eBay, Twitter, Netflix are either entirely JVM or predominantly JVM, and even Facebook is making growing use of the Java.
Most of the shifts you're seeing is among non-JVM technologies. It's mostly Pythonists that switch to Go and Rubyists that switch to Elixir/Node.js, etc.. The JVM was never the biggest player in the "fast application development" arena -- at the beginning there was VB, and then Perl, and then Python/Ruby and so forth. I see no signs that there is greater movement away from the JVM -- mostly among those who realize they're better served by the "fast dev" platforms even at the cost of performance -- than towards it -- by those realizing they need the best the industry can offer in terms of performance/monitorability/tooling even at the cost of slower development.
