The real benefit, in the hands of a DM who can frame the prompts well enough, is indeed being able to author on the fly text - that can be edited/changed/redone and reworked - it's a jumping off point type tool - not necessarily and end in and of itself. I'm looking forward to future more refined versions that reduce the mistakes producing contradictory text. And a better/broader range of understandings of TTRPG rulesets.
