Seems to be that "what would happen if NixOS and Qubes had children" scenario. Glad to see Nix propagating itself, the fundamental ideas are right, maybe what we need is different people trying to implement more stuff atop it, so even if NixOS dies the ideas live on.

Doesn't seem to be the case. They are using Nix too(the package manager), but I couldn't see other similarities.
I think they are completely different from NixOS. For starters, they want to run every app inside crosvm.
From their Design page:
