Text to Game will be a huge, if a solo dev can create a AAA tier game that is actually fun to play, from scratch? That's when shit gets real.

Although I think AI completely generating a game from scratch is likely to produce a lot of mess and incoherence if it's not using AGI. In the nearer term, I would expect game developers to act more as directors, in the sense that they will assign particular tasks and modules to an AI, which the director will then stitch together into something coherent and compelling.

For instance, creating dialogue for NPCS might be a task of manually designing a dialogue tree, then using AI to generate the text, curating and pruning portions of it until it looks right, after which you'd generate your voices, facial animations and design of the NPC itself all via AI.
