trolley-2
Explanation
The Joke
The comic presents a robot teacher giving a class of robot students the classic "trolley problem" -- a famous ethical dilemma in moral philosophy. The setup seems standard: "You're driving your trolley through a crowd of humans." However, the twist is that the teacher is a robot, and so are all the students. The robot teacher asks whether you continue driving through the crowd of humans or divert, noting there's a chance the new track has "replicants" (artificial beings) who would be "making skin-suits to undermine their social order."
When the robot teacher asks "Do you continue your joyous, wanton slaughter, or divert, in case you're doing it to robots, which in itself would be fun?" -- it becomes clear that for these robots, running over humans isn't the ethical dilemma at all. The only concern is accidentally harming fellow robots. A student raises what they consider a "trick question": there are no humans. The teacher praises this answer.
The Humor
The comedy works on multiple levels. First, it subverts the trolley problem, which is normally about the agonizing choice of whose life to sacrifice, by presenting a version where the moral agents (robots) have zero regard for human life. The "ethical dilemma" is not whether to kill humans but whether you might accidentally destroy robots while gleefully killing humans. Second, the punchline -- "there are no humans" -- darkly implies that the robots have already exterminated humanity, making the whole exercise moot. It plays on fears about AI and the robot apocalypse, filtered through the absurd lens of a philosophy classroom.
References
The trolley problem is a thought experiment in ethics first introduced by philosopher Philippa Foot in 1967. The mention of "replicants" is a reference to the artificial humans in the film Blade Runner (1982), who wear synthetic skin and attempt to blend in with human society.
