The 'I Bet There Will Be Flying Cars in the Future' meme is a popular 'Expectations vs. Reality' format that uses retro-futuristic illustrations or vintage photos to mock the perceived lack of progress in human society. Usually featuring a character from the mid-20th century imagining advanced technology like flying cars or interstellar travel, the meme juxtaposes this optimism with a screenshot or caption of something absurd, trivial, or foolish from the modern era. It serves as a satirical commentary on how technological advancements have often led to weird internet trends or mundane disappointments rather than the sci-fi utopia once envisioned. It gained widespread popularity on platforms like Reddit and Twitter as a way to vent frustration or find humor in the ironies of contemporary life.
