The ‘why not’ is not from the perspective of the industry - it’s from the perspective of the customer. Can you automate several tasks by using AI during game development? Sure. Will it translate into a better price or a better experience for the end-user? Let’s see.

Let’s say you give AI the unimportant tasks. You manage to reduce a lot of waste and maybe optimize your workflows. You improve efficiency. Maybe you can make more games in a shorter time span. Will you be willing to sell the games for less than the standard $60? I find this unlikely. This impacts me as a consumer - why am I paying for your improved tools with my money?

Let’s say you give AI the big tasks - you make it write story, generate graphics or code. But AI’s current level doesn’t allow for originality, or even cohesive thought. You’ll be churning out garbage until your AI is actual intelligence. This again impacts me as a consumer - why am I sponsoring your experiments with my money?

So - sure, let the companies throw themselves at this. But I’m not investing my own cash in their research.
