The TPOT (The Person On Twitter) and Post-Rationalist (PostRat) memes emerged from a highly specific subculture of tech-focused, philosophical, and rationalist circles on X/Twitter. Characterized by an obsession with artificial intelligence, effective accelerationism (e/acc), and complex social dynamics, these memes often use lo-fi imagery or specific animal avatars like rats to signal membership in the 'weird' side of tech. They serve as a form of shorthand for community-specific ideas, mocking traditional intellectualism while embracing a chaotic, fast-paced digital identity. As these circles grew, the 'PostRat' aesthetic became a badge of honor for those navigating the intersection of deep theory and high-speed internet shitposting.
