ECS has really nothing to do with this. ECS is just a specific way to store the internal state of a program, fundamentally no different from other data structures.
Also, a good game is far more than just text and images and current “AI” can’t even generate those individually. A game needs significant thought put into things like game loops, story arcs, balancing,… that are non-obvious when existing games would just be training data. Not to mention that using an existing game as training data is both non-trivial and also we just don’t have the vast amounts of them that current systems seem to need to produce anything even half-way decent.
ECS already makes it a hundred times easier for me to conceptualize game mechanics, modify and extend them. Giving AI the ability the ability to create data separate from systems that use them will make it much easier for it to build a game. I don’t believe for a second it will be able to write functioning object-oriented game code for example. It will likely be best if it avoided coding via a text-based language altogether, and use visual scripting or another system based on chaining logic blocks together. But that still counts as the “system” part of ECS.
Visual programming has been tried and tried again and failed every single time. Mostly that is because graphics are just not very good at abstraction and programming is all about abstraction.
