Crystal has already "taken off" for me, in the sense that it does everything I need it to do. The standard library is replete with http client and server, as well as JSON, and a host of other useful bits, just have a look: https://crystal-lang.org/api/ https://crystal-lang.org/api/ Wrapping of C-libraries is a relatively painless experience: https://crystal-lang.org/reference/1.8/syntax_and_semantics/c_bindings/index.html https://crystal-lang.org/reference/1.8/syntax_and_semantics/... I can use any/all command-line utilities with an IO buffer (image processing, other out-of-band processing) The stock "DB" module supports Sqlite, MySql, and PostGres out of the box. SPEED: anyone "sticking" with RoR is not paying attention here: Crystal is a compiler and spits out a binary executable with low memory usage compared to it's interpreted cousin. This binary executable can be run by systemd as a normal system service, started with command-line options, etc. Apples-and-Oranges comparison: I've turned a nodejs-based app that used roughly 600mb memory into an executable using 12mb. The latter has also not leaked any substantial amount of memory after running for 5 months straight now (still says 12mb) so, take that as you wish... For me, Crystal has already arrived. I don't need group approval for this to be the case. I can happily use version 1.7.3 for the rest of eternity, so I don't see this rug being pulled from out from under me in the near future. Perhaps use private shard repos if this is your actual concern.
