I wouldn't be so sure about that. I do think there's a bit of scope creep, especially with the LLVM replacement stuff, but I don't think it's bad enough for the language to never come out. Most notable languages have at least one large corporate sponsor behind them, Zig doesn't.
I’m a casual user and the 0.16 changes scare me. I tried multiple attempts now, even with full LLM support to upgrade and the result is just a) painful and b) not very good. I have high doubts that the current IO system of 0.16 will make it for another release given the consequences of their choices.
