I recommend you to watch Andrew Kelly interview[0], while I'm not the target audience of Zig, I don't see him driving away any user. Also Jai as for now is a non existing language, just a selected few has access to it, but Jai approach is a kitchen sink, from what I saw it is all over the place in terms of features, now Zig vision feels cohesive.
Thanks for sharing that link. That guy seems so nice, quite inspiring.
