They seem to be doing fine. Tigerbeetle and Ghostty are two projects that continue to do well and are written in Zig. The foundation’s funding also seems to be doing well. They are continuing to make releases.
At work I use Claude, but it is a considerably larger and quite complex codebase. I use LLMs a lot, but it is a common weekly occurrence for me to correct misconceptions, bugs, or overengineering from Opus/Sonnet (Opus plans and reviews, Sonnet implements).
