Yeah that's why I said it depends. :) periodization is tough. 18 months, four years, six years, and 9ish years are all valid, depending on how. What I mean to say is that it's already been quite a while, and now that it's making its way into distros and required for building Firefox and all that, I think it has even more of a chance of sticking around for a long time, given that it was around for quite a while when it wasn't even a viable "real" language. I don't mean to insinuate that today's Rust is mega mature because those old Rusts exist.
