> to more performant runtimes and architectures in response to operational concerns at scale, which have a tenuous link to language
The runtime performance and the language are deeply linked. None of the dynamically typed runtimes you mention are actually performance competitive with JVM languages.
Luajit and SBCL are very much performance competitive with the JVM? Why do you say that they're not?
Random example benchmark: https://madnight.github.io/benchmarksgame/lisp.html
That's someone's 8 year old mirror of the benchmarks game website.

These mean nothing. The C/C++ implementations use SIMD intrinsic while Lisp doesn't (it should have used sb-simd).
Huh. And after eight years, SBCL and Java are side by side, still.
They absolutely are. Maybe not if the only thing you’re benchmarking is something completely CPU bound like signal processing/math, but they’re definitely competitive for tons of real use cases.
They don’t really need to be though. They take far fewer tokens and are still faster to develop with
