I partially agree. Coding is not the hardest part for a large portion of indie games. You can in theory build an AI-coded game that sells well if you have the right art and gameplay.

But many top games have complex engines and online services that require technical mastery beyond the current AI capabilities. For those genres, engineering is a huge barrier of entry.

For a not so extreme example, you won't vibe code Cyberpunk 2077 while just taking care of art and gameplay ideas. Gosh, humans could barely pull that one off!
