Here's an example of this regarding the recent indie hit "Mina the Hollower." They were recently interviewed and asked the question "What is Yacht Club's stance on AI and has AI been used in the production of Mina the Hollower at all?" to which their reply was "We all got caught up in AI fever like the rest of the world, but we didn't find it was very effective for what we're doing. Maybe our work just isn't that generic! We've found some ways it can help... like Google or a thesaurus, but it hasn't affected what's in our game." [1]
It's hard to immagine that even the best AI model would result in anything better than a marginal reduction in release timeline. Like maybe for such projects one could spend $X00,000 worth of tokens for maybe like a %single-digit-percent reduction in time to release. Marginally good, maybe even project saving, but not any larger a paradigm shift than Unity was.
