Sadly, there are many other reasons, too. I met a family of immigrants. I learned through their eight-year old son his parents lost their jobs, couldn't find legal employment, did not speak english. As they were at a shelter, I imagine they were decent candidates to be picked up by ICE.

Nonetheless, I agree with your post. This is a solvable problem but it is only solvable at the housing level.

9p is indeed a great technology—I would have also thrown in utf-8—but most of plan9's ideas remain quite fringe. I would pay a ton of money for an OS with both bind and browser support. Plumber is still leagues better than anything offered by macs/linux/windows.

That said, I don't see "fringe" as being mutually exclusive with "legitimate". TempleOS had some features that other OS's could use, too—its use of hyperlinking is actually really cool.

I know that Russ Cox & Rob Pike both still use plan9.
