This is a neat trick and clever technical work, but is it useful in practical terms?
Like, wouldn't you just download the binary that's been compiled specifically for the platform and architecture that you're using? Rather than relying on a potentially quite fragile method of cross-platform execution.
In a way it kind of reminds me of Urbit. Very clever, very cool, but also very niche and more of a hobbyist showcase project than anything else. Not that there's anything wrong with that of course.
