The style here suggests a split between tools and content, which is something I'd love love love to see emerge. Having one and only one app be both viewer and toolkit feels like a convenience trap, one that NeXT tried to fight (as did OLE) and that feels unlikely to ever be turned back from, but I want to dream. This UI doesn't materially move us towards a more aggregative/accreted system of systems model, but it visually suggests some of the absurdity of there being such heavily coupling, if the UI is really incidental that floats atop. I'd love to see this pushed further, to emerge into a multilayered information world, where Rainbow's End discourse piles up and forms trees out and up.

I hear folks on contrast concerns. I have hope though. I really like the de-emphasis on compute. On tools being less the thing, on the content first, on getting computing out of the way, making it ambient. Unboxing the content, unframing it.

The glass refraction seems like a an amazing leap forward. Material has been around forever and there's all these developer docs showing the stack up of layers, implying the depth of the system, but in the 2d user world everything is flat, composited into indistinction. The visual sepration, allowing semi transparent motion, but using refractive style to clearly separate the layers, adds such clarity that it feels obvious in retrospect immediately to me.

I still lack hope that XR is going to be a huge huge thing, that it will be comfortable over time, but it makes such sense to me that XR would inspire & lead this shift, to depriotizing the UI & emphasizing the content.

I'm stressed a bit trying to imagine the transforms required to make this refraction happen. I don't think CSS is going to be enough. The new CSS Painting API ("Houdini") also seems more generative than able to modify & script what is?
