I think this merits a lot more further exploration going forward. There are some unintended consequences that can come from bots, both good and bad.
Bots are tools and not inherently bad or good, depends what they are used for.
Currrently I see the platform as vulnerable to abuse to auto voting that can lead to winner take all effects. That would be very bad for the platform since it will slow growth.

On the other hand bots expressly designed to look for underappreciated content might be a good purpose but ironically, because they are not as good as humans to distinghuish quality content (yet) this effect for good will probably be not as powerful to cancel out the bad effects.

The winning solution is probably a centaur: a team consisting of bots with humans. A first rough filter of content that are potential candidates then manually looked at by humans for proper curation. (Curation is not about upvoting by the way)
I think it is good that there is experimentation with bots, but the effects have to be watched closely before they get out of hand. As with advertising, there can be perverse incentives if the content here would be optimized to please bots as opposed to humans.
