Your second paragraph does not follow, at all, from the first. These are completely orthogonal demands.

The gaming industry is absolutely overwhelmed with outrageously inefficient, garbage, crash-prone code. It has become the norm, and it has absolutely nothing to do with AI.

Like https://nee.lv/2021/02/28/How-I-cut-GTA-Online-loading-times.... That something so outrageously trash made it to a hundreds-of-million dollar game, cursing millions to 10+ minute waits, should shame everyone involved. It's actually completely normal in that industry. Trash code, thoughtless and lazily implemented, is the norm.

Most game studios would likely hugely improve their game, har har, if they leveraged AI a lot more.
