I've had the opportunity to demo their product on 3 different occasions. Each time it was a clunky interaction, stopped working in the middle of the demo, and I left thinking my kid's Playstation VR could run circles around their tech.

they allegedly had an insane demo for investors only, before around 2016 (at least that's when I heard of it) you needed to sign an NDA to even get in the room to see it.

The consumer product is quite lacking compared to what people said was a demonstration of game changing technology.

So: NDA, exclusive demo, controlled environment.

It makes it sound to me more like a Séance (with its usual implications) than anything else. Or, for an easier to understand analogy, selling a Disney ride as if it was real.

Fred's Plastic Fork Factory can tell you that you can't moonlight and can fire you if you do.
