There's a whole category of utopian developer environments and languages with far bigger aspirations than they were able to achieve but that still influenced others. Smalltalk being another example.

I keep hearing about it and its influence, but I can't really figure out if it's active or dead or even If I can use it on a virtual machine or so. 9p.io doesn't seem to even load on my machine
