It wouldn’t be a good compass if nobody had strong issues with it:

1. System vs Toy is not opposed to each other. Should have been system vs abstract or useful vs toy or whatever
2. Where LISP? Best language missing makes graph bad

Edit: before people tell me there’s already ‘obsolete’ on the graph, no, there’s loads of obsolete languages that are still useful, and many more new languages that are either built for fun or not used for sad or good reasons.

Edit2: I’m also halfway sure that brainfuck is older than rust (but don’t wanna look it up). But if that’s true your axis mean several things at once anyway and you should feel bad (not really though).
