Hi there! I've been on-and-off working on TacOS for a few months, which follows some UNIX-derived concepts (exec/fork, unix-style VFS, etc) and is now able to run a port of Doom, with a fairly small amount of modifications, using my from-scratch libc. The performance is actually decent compared to what I expected. Very interested to hear your thoughts. Thank you!

A few months work by one guy and already more capable than the Hurd.

Imagine what you could accomplish given 35 years.

It is no way capable than Hurd. It is a cool project though. Have you used Hurd recently? It can run a modern desktop.

I searched YouTube for actual evidence of Hurd booting to a desktop and only found two videos of Hurd freezing during boot, and a third video of RMS explaining to a very confused convention attendee that he's "never installed GNU slash lynn-ox" because he could just ask someone else to do it.

No videos of Hurd running Doom either, but anyone is welcome to create one and share.

Hurd is for sure a failed project and it can't realistically run a modern desktop as claimed, but it's more capable than you give it credit for. For example, see:
