> You don't have to be an amazing programmer to be an amazing game designer

That has been true even without AI.

Solutions to create games with barely any programming knowledge have existed for a long time. You can create a full featured Unreal Engine game with just using its visual scripting language.

Lots of amazing games have absolute dogshit code. It doesn't matter. You can write super simple, procedural code without any fancy abstraction and just get the job done.

Programming is the easiest part of game dev.

Plus you don't have to be a solo dev. Sure, just being a game designer might be hard but if you bring artistic skills to the table as well then you are golden and can partner up or outsource the programming if needed. Honestly people with an artistic background often do much better than people from a software engineering background who are used to overcomplicate things.

So no, programming was never the hurdle and AI doesn't help here. It just helps people to produce more slop faster.
