Even if it stops being updated? The internet is replete with old sites that are still up but have long stopped getting updates. What made this unique is that it was continuously updated for over 20 years. If the price of continuing that is AI generated content, at least as a placeholder until which time the site owner can handcraft the episode summaries, isn't that a price worth paying?
All else being equal, the later the point in time when the author chooses to stop updating the site is, the more special the site will be.
The question is, is the site more special if it stops being updated now, when it's made up of exclusively handcrafted content, or if it transitions to less labor-intensive/AI-based content generation for new updates, and continues being updated for many more years.
