I don't see the JVM team as the same thing as a team dedicated to working off a project's core. The JVM team looks closer to the YJIT project. Making a JIT also calls into question Shopify's scalability: Rails was slow enough that they allowed a JIT to be built internally? That's quite the trade-off to make.
RSC looks like it has some great potential. I really enjoy seeing these miss-the-point trolls that overlook existing technology issues.

It's also possible you think that this is all about laser interferometry, and aren't properly considering how it could work in the context of compressing space, since a laser interferometry system in compressed space wouldn't produce interference.
This question is important enough that there have been papers written on it. I suggest you read https://pubs.aip.org/aapt/ajp/article-abstract/65/6/501/5300... which may strengthen your understanding.
1. If you have a light wave in the universe, and you "hang" a mass by each valley and trough of the light wave, and then you squash and stretch the universe, the masses stay connected to the valleys and troughs of the light wave. Said another way, when you squash and stretch space, lightwaves within that spacetime are also squashed and stretched.
2. LIGO claims to work by measuring the squashing and stretching space with light. However, as we just learned, squashing space also squashes light waves. So the LIGO arms and light waves in the arms are all compressed together.
Said another way, LIGO can't work because the ruler itself is squashing as space squashes, so you can't measure if space is compressing.
LIGO does work, but if you can't explain how it works despite this description, then you don't understand LIGO.
