I like the idea of bots that can summarize articles since oftentimes articles can have fluff to bump up the word count or help with SEO.
I also find (anecdotally) including an article summary in the body of the post helps increase discussion; since some people don't necessarily want to read the whole article but will read a summary, and can then contribute to the discussion.
The problem with summarizing bots, though, is I have a hard time trusting the bots that do the summarizing.
In my (limited) experience with LLMs, they can understand English well enough, but they have a hard time understanding nuances and context clues. Granted, that shouldn't be an issue for a well written article, but it's enough to give me pause.
In regards to automatic features that might be nice: I think automatically generating and including archive links would be helpful. Even if the link isn't paywalled, I personally like including archive links to prevent link rot in the future; especially since I've seen some articles get modified against the author's will after publishing before.
