this is no doubt all vibe coded

It might not be entirely so. I've watched their youtube announcement (less than 2 minutes video), and they talk about starting this project back in 2019, so there's no way it was all vibe coded. I don't doubt that the recent stretch was probably heavily using claude, but I wouldn't call it cuckcoded if they truly started back in 2019 before LLMs were anywhere useful.
