Sven Harvey included "I, Borg" in a list of 25 "must watch" episodes of the series compiled for Den of Geek, describing it as "a wonderfully written and executed episode which lays a path for later developments". Zack Handlen gave "I, Borg" a grade of A- in his review for "The A.V. Club", and while he was disappointed that the Borg were made less "nightmarish", the question of genocide that hung over the episode and the expansion of potential story ideas from the plot made it worth it. In a review of 25 greatest science fiction episodes by SyFy of the years between 1992 and 2017, "I, Borg" was the only "Star Trek" episode selected, although this excluded any episodes before 1993 or so.
