The Joke
A woman asks a man to imagine what the world would be like if humans had very long lifespans (like thousands of years). The man proceeds to enumerate all the ways society would be different: grandparents would literally come back from beyond the grave to nag you, parents would be even more overprotective because babies would be rarer (since reproduction would slow down with longer lifespans), babies would be more annoying because they would cry for years, humans would be even more self-centered, language would no longer be needed since humans would have evolved past it, and so on. Each observation gets increasingly absurd and pessimistic.
The punchline comes at the very end when the woman, frustrated by his relentlessly negative take, says something dismissive, and we learn that most people just say "that would be cool" when asked this question -- implying the man has massively overthought a casual hypothetical.
The Humor
The comedy derives from the contrast between a casual, whimsical hypothetical question and the man's exhaustive, deeply pessimistic sociological analysis. Instead of giving the expected fun answer ("That would be awesome!"), he systematically dismantles every aspect of the fantasy, turning an appealing thought experiment into a nightmare scenario. This is a recurring SMBC theme: taking a simple premise and applying rigorous (but darkly humorous) logical thinking to arrive at uncomfortable conclusions. The final panel serves as a meta-joke about how most normal people respond to such questions versus how an overthinking nerd does.
