Debating the usefulness of hn commentary is a somewhat philosophical issue, but I think it's entirely fair to draw parallels between what is, not what might be.
Gemini Ultra is self-evidently not ready for production. What the issues are? Who knows, but in a game that as of right now is mostly about reducing the amount of brute force required, something as "simple" as not being efficient enough is actually not something to gloss over. If your engines entire stick is having the greatest graphics but you can't make it run at acceptable fps, well, then it's not actually a usable product.
A LLM that is not actually released could very well be in a comparably dire state and fixing it while also delivering on the promised performance might be entirely non-trivial.
