I recently read about a 4 gigabyte uncensored package that you can run locally. Seems entirely possible now.DAN is great for certain things but it's more of a gag and it can't just be "switched on" for continuous use (you have to often remind it to be a DAN, which seems to reset its memory even within the conversation).
I look forward to the day where these sorts of systems can be used in-home with your own rules applied, but I imagine that's far off.
