I hadn't heard of Jai yet, but wow! That's a lot of hype (and even tool support) for something that doesn't work yet.
At first glance, Zig vs Jai reminds me a lot of the Linux vs GNU Hurd thing (or a lot of other "worse is better" examples). A couple of geniuses locking themselves up telling the world "Just wait! It'll be awesome!" seldomly produces something that lasts.
Yeah I guess. The only charitable thing I can think to say is that maybe they've tried all the others and found them lacking somehow (what language is perfect, after all?) and so they put their hopes to the one as yet untested.
It could, theoretically, be perfect. Since it's all theoretical at this point I mean.
