Their intent in making the reference is a bit vague, but they seem to be referring to the recently released series of the same name, and maybe drawing some kind of parallel between AI technology and the mind control virus depicted in the show, which I haven’t seen yet myself, so I am only speculating:

https://en.wikipedia.org/wiki/Pluribus_(TV_series)

> The show follows author Carol Sturka, played by Seehorn, as the rest of humanity is suddenly joined into a hive mind that seeks to amicably assimilate Carol and other immune individuals into the mind. The title of the series refers to e pluribus unum, a Latin phrase meaning 'out of many, one'.

> Set in Albuquerque, New Mexico, the series follows author Carol Sturka, who is one of only thirteen people in the world immune to the effects of "the Joining", resulting from an extraterrestrial virus that had transformed the world's human population into a peaceful and content hive mind (the "Others").
