They focus on Rust because it's the global standard everything is compared to these days. It would be good for it to have some competition, even if we also wish its critics were more careful in their phrasing.
The only point is that it's not weird for Zig to compare itself to Rust.
Also, not only it is hard to see which big corp would make using Zig unavoidable, AI driven programming makes most languages irrelevant, it is a matter to ask what flavour should be output be.
Which is like, why are we even arguing for manual memory management, when is the LLM doing the work.
