Incredible file system design for one thing.

As another file system idea, a git based implementation would be purely functional. Something along the lines of this project https://github.com/presslabs/gitfs.

The opportunity to change how we look at file systems here is huge. A git based filesystem could allow diff'ing user data. This would effectively give the timeline of Pages or Numbers on a Mac.

Git is a tried and true management system that is purely functional in nature.

I'd strongly prefer something pijul based over something git based, as it'd have even stronger guarantees.

No. I'd watch Tron and vote against this.
