You're free to like Crystal of course, but for me even for long running tasks (almost my entire desktop, including my wm, terminal, editor are Ruby - I still use Ruby for almost everything; if anything, for more than ever), the Ruby ecosystem beats the steadily diminishing performance gap between MRI and an AOT compiled language to the extent that even going to TruffleRuby where I could keep almost all of my code, is rarely worth it for me.
But my main point was that people who do want a fast Ruby should be aware that Crystal isn't a Ruby in any meaningful sense - if you like Crystal for Crystal, by all means use it.
