The 'All Tomorrows' meme originates from C.M. Kosemen's 2006 speculative evolution book, which depicts the billion-year odyssey of the human race as they are genetically twisted by an alien race called the Qu. The meme gained massive traction on YouTube and TikTok through lore deep-dives and transformation videos, often comparing modern life to the bizarre and horrifying forms of post-humans like the Colonials or the Mantelopes. It is typically used to represent extreme physical or mental change, the terrifying nature of deep time, or the feeling of being reshaped by mundane modern inconveniences into something unrecognizable.
