I'm not talking about using AI to help code, which seems obvious, the parent commenter is talking about people building game engines and assets from scratch in a weekend. Meccha Chameleon was built on UE5[0], and Big Walk (the game you're talking about where the devs solved a bug using AI) is using Unity. Both of these games, I believe, took longer than a weekend to create.
