They discuss Dreams in the video and even explain Brick rendering.

WebXR hasn't been supported for 10 years so they control their own AR market.

I believe they are using the open source PlayCanvas splat integration.

To display the closeups I'm using super splat in the browser and in the training tool I'm using my own hand written renderer. Mostly so it's easier to swap out splats during training

This is a code editor with the same url idea:

If you were blind would a screen reader read the documents? Thats not a hack.

Placing a black box on the text isn’t a redaction any more than placing a sticky note would be. No reasonable person can expect a sticky note to permanently prevent readers from seeing text and no reasonable person can expect a black overlay box in pdf to prevent reading text because this is literally a fundamental feature of pdfs as a layer format file

"BNF itself emerged when John Backus, a programming language designer at IBM, proposed a metalanguage of metalinguistic formulas ... Whether Backus was directly influenced by Chomsky's work is uncertain."

I'm not sure it required Chomsky's work.

Oh, lots of stuff gets invented multiple times, when it's "in the air". Nothing special about Chomsky here. And I wouldn't see that distracting from this particular achievement.

Couldn't it be a simple reboot to switch back to normal linux?

Yeah JSON compatable is very different from convertable.

You have to encode the type of all the binary data. Does that make it serialization?

GLTF is like this too (or PLY)? The main difference is the format of their headers? Just by reading the header you can parse the binary data. I'm surprised BSON and any of the other binary JSON formats they list don't support reading the memory layout in a header.
