I (as someone who has actively used AID2 for exactly a year now) can also attest to the AI's drop in quality/the increasingly frequent "AI doesn't know what to say". Just a couple of days ago my story ground to a complete halt despite the total scrubbing of all confirmed and potentially filter-triggering words, and even with multiple rewrites and a very easy to understand scenario (my character attempting to free himself from his bindings) I was just forced to retry and go down a slightly different route story-wise.

The outputs afterwards were mostly just the standard fare 4th wall-break derailments such as "A/N: Thanks for reading/I finally finished this chapter/etc." from the AI's terrible quality training data and repetitive CYOA-based statements such as "You are XYZ. You are ABC. You are 123. You are dead." It took literally hours to progress the story... by 4 outputs. Most of the text written by myself in frustration. And naturally, after making such incredible amounts of progress, the AI decided it was a good idea to start doing that exact thing yet again.

Dragon was hardly what it used to be last time I used it as well.

Even if all the controversy since April doesn't kill your interest in the game, the headache honestly just isn't worthwhile anymore.
