This meme originates from the 2018 Marvel blockbuster Avengers: Infinity War during a confrontation between Doctor Strange and Thanos on the ruined planet Titan. When Strange asks 'Let me guess, your home?', Thanos uses the Reality Stone to project an image of the planet's former glory, sighing, 'It was. And it was beautiful.' The template is widely used by internet users to contrast a disappointing current state with a nostalgic or idealized version of the past, often applied to decaying video game franchises, gentrified neighborhoods, or evolving social media platforms.
