The 'You're Weak / I'm You' meme stems from a dramatic confrontation in the 2019 blockbuster Avengers: Endgame. In this scene, the 2014 version of Nebula confronts her future self, calling her weak for defecting from Thanos, to which the future Nebula poignantly responds, 'I'm you.' Online, this template became a staple for comparing different versions of the same entity, often used to mock personal growth, software updates, or the cyclical nature of history. It perfectly captures the irony of criticizing someone who is simply an earlier or later iteration of oneself, making it a favorite for glow-up posts and self-deprecating humor.
