The most visible uses are stupid - but the technology can easily improve actual human effort. Starting from text and churning out ten thousand tiny variations is just a demonstration of how far it can be stretched. You could feed in a sketch and get get a finished texture, with all the wonky false-color channels. You could change a voice actor’s performance to sound like someone else giving that performance. You could filter in-engine footage for cutscenes that look eerily realistic while staying on-model.
None of which will fix the scope creep that’s slowly killing the industry by turning every project into a five-year-long gamble the employs a thousand people and still manages to crunch for eighteen months straight. Guys. There’s game jams where teams that’d fit in an elevator produce fun products in a matter of weeks. You wouldn’t need to fixate on magical future technology if you committed to releasing a game about once a year… instead of making ev-er-y single pitch the biggest and bestest and prettiest thing evarrr.
