Dear sweet Oghma. We can’t even get rid of it on TTRPGs.
Eh, there’s a lot of valid things to be skeptical about. Using these tools as a DM is fundamentally different from using them as a massive corporation, as you’re not considering replacing your team of talented artists and writers to cut costs.
That said, done right, I also think this could be amazing. Legally train these models on the wealth of historical D&D art, and provide it to DMs to use during their campaigns to make maps, art for places the DM is describing on the fly, all of these things that no artist could possibly make because these locations are being invented on the fly as the players throw a skilled DM curveballs. D&D feels like an ideal “problem” for a lot of the “solutions” AI has to offer.
