what would happen if we want to install, for example, two different versions of ruby at the same time? This is treating the symptom instead of the root cause, that being ineptitude to design backward-compatible software. We as an industry should fight such band aids and take a stand. Yes, designing backwards compatible software is hard, but exactly that is the difference between engineering and amateurism. And if one is getting paid to program, I’m going so far as to argue that it’s one’s job to have their head hurt solving such difficult problems so that users of computers don’t have to.
