Passing the Turing Test doesn’t seem to have an obvious connection with the ability to create a good game. I could (hopefully!) do the former, but not the latter.
That said, I do agree it feels as though we’re now teetering on a tipping point for AI and are going to see it crop up in more and more arenas, including more games. It will be interesting, and probably a bit scary, to see what it does well and what it does badly … at least to begin with, before it gets better at that too!
I agree that procedurally generated RPGs seem like an excellent use case to start with, whereas the more handcrafted, story heavy RPGs I like are probably going to be further down the road. Though I suppose you can argue that even few of those are original enough that they couldn’t be generated by an AI that had been provided with lots of info about other such games!
From the, admittedly little, I understand about AI, there’s still going to be a significant role for humans in the immediate future in training AIs, confirming what works and what doesn’t, and preventing them going rogue in some scenarios. But who knows how long that’s going to be the case?
