[I literally had this thought in the shower this morning so please don’t gatekeep me lol.]
If AI was something everyone wanted or needed, it wouldn’t be constantly shoved your face by every product. People would just use it.
Imagine if printers were new and every piece of software was like “Hey, I can put this on paper for you” every time you typed a word. That would be insane. Printing is a need, and when you need to print, you just print.
Sounds like you forgot to consider the energy cost of developing each AI model. Developing and maintaining a model is vastly more energy intense than 3d game dev. Keep in mind that you can ship a 3d game and ramp down gpu use for dev. But an AI model has to be constantly updated, mostly by completely retraining. Also, noone was clamoring to build massive data centers just to develope one game. Yet they are for one model.
