Reproducibility.

In a nutshell, it's a purely functional Linux distribution. That means all changes you make to your system are non-destructive. For example, you can always roll back to a previous OS state, which is represented by a hash computed from all packages installed, and all options you've set. In turn, package hashes are computed from the package sources and all inputs (buildtime and runtime package dependencies).

I feel like one day this will be how all OSes work and we'll look back and wonder how we ever found the old way acceptable.

Then another 10 years later, we'll think this is all too complicated and reinvent the wheel/simplicity.
