Gonna copy pasta one of my previous comments because it's relevant again:

I’m going to argue that how you use the lying machine determines if it’s slop, not if you use it.

“Generate a character profile for Alexander the blacksmith.” Slop.

“Ask me questions about Alexander the blacksmith so I can further develop his character.” Not slop.

“Summarize everything I explained about Alexander the blacksmith in the format of a wiki article.” Could be slop, might not be, depends on how diligent you were about not letting the lying machine have creative control. Needs to be reviewed for accuracy of course.

And for the record, I was a DM for years before generative ai was a thing. Running a campaign is ton of work, even with shortcuts. Don’t insult your DM like this.
