You’re not wrong about a lot of these points but I think it’s worth pointing out that each AI application will basically be a separate tool.

For texture work, these tools will be used immediately and probably only have beneficial effects. It will even give premade assets a nice feel AND you can use AI to turn one hand-made texture into a large amount of unique assets. Which helps indies by avoiding the copy/paste feel of their assets. Same is true of models but will take more time for that.

As for voices, what you said is true. A bad human voice is still mostly better than AI. However if you have a lot of dialog or just want to play test, the AI voices are great for that before you ask a human to do the lines.

And as for story and script dialog, AI is already pretty good at this but the application is important. Games that overuse AI to write their story or characters will stand out as really bad. But when used correctly, AI can change generic filler into interesting plot. Or make people say unique things every time you see them. Combine that with voice generation once it’s good and we’re in for some very cool applications.
