<NiAsterisk>in addition to what I said (if you are still there, i don't see parts and quits), languages will continue to exist even without an editor to use, or even without computers if you break it down to the very basic level. the knowledge of the language is out there, and disappearing would in some scenario involve people (disappearing, dying, stop to work with it) and no one getting currious about that one particular language anymore
<NiAsterisk>ever. that's the very very very short version of a languages death.
