It is nice with a lot of innovation now in the ahead-of-time compiled languages camp.

What worries me is the fragmentation, and the fact that no one language seems to check all of the (subjective set of) boxes for a general purpose high-speed, ahead-of-time compiled language [0].

E.g, Crystal seems to be the only one supporting a modern concurrency story (similar to Go), but has a huge problem with compile times.

Nim looks nice in many respects, but last I checked, they don't have anything like Go-like concurrency. Maybe not on everyone's wishlist, but as the world move toward flow everything/everywhere[1], I personally find this to be a problem.
