what went wrong?

Linux happened

Given how shitty driver supper linux-libre has I can only imagine how shitty GNU Hurd must be

>userspace kernel
>message passing
What more needs to go wrong before Stallman realizes it's inherently shit?

The giant overbloated microkernel from what I've read.

Hurd? More like TURD.

a unix-like microkernel is a poor design decision. it will always end up very slow because microkernels rely so much on ipc, and unix ipc has high overhead.

Functional programming isn't sufficiently well explored yet to pull microkernels off.

A microkernel is de facto incredibly hard to debug.

Combine this with the technology of the time and the fact that GNU was ported to Linux a year thereafter, and it's no surprise that HURD became what it became.

The impetus to make a fully functioning kernel when you already have one is practically nix, which is why it became a research project.

With that in mind, most kernel developers "break their teeth on HURD", so it's not like it was a complete waste of resources. The merits of HURD are just more passive. HURD created a whole generation of kernel hackers that wouldn't have otherwise been there weren't it for the fact that there was a need for a fully free operating system.

Good one!

How will they ever recover?

It's weird how blatantly impractical functional programming is compared to how useful it is in a research environment. I mean, besides emacs, there's very little proof that functional programming can do anything useful, yet, basically every other language has benefited from research into functional programming. HURD is, in a way, incredibly representative of that.

functional programming has nothing to do with microkernels

Would it be even possible to create an OS in a purely functional language?
Since functional programming is all about having no state and immutable data and a Turing machine has by definition state and mutates data by reading instruction doesn't this make functional programming completely inappropriate for a low level OS programming?

Solution in search of a problem.
