I was half joking. Folks keep saying everything will get rewritten in Zig, so I played along with that. Nothing serious behind it.
With only half serious intent, I think only the real wizard types, like Jarred Sumner (Bun) and Mitchell Hashimoto (Ghostty), who understand both low level systems and higher level languages, should be writing big tools in Zig. The tough part in the next few years will not be building things, it will be keeping them alive if the authors step away or the ecosystems move in a different direction.
