In his inspiring DLD26 talk, digital pioneer Aleksandar Stojanovic unveils the Tesseract, “a collaborative memory monument and civilizational time capsule.” The project by the DARI Foundation aims to safeguard the human legacy in the age of superintelligent AI.
“Machines are now creating more content than humans do”, Stojanovic points out. “Art, history, truth, memory, legacy, it’s all dissolving in an ocean of synthetic content.”
The Tesseract aims to “ensure that the human essence won’t vanish but flourish”, Stojanovic says.
Composed of one million “memocubes”, the Tesseract is itself a cube, measuring 11 meters on each side. Memocubes consist of quartz glass that has “the ability to survive in extreme and harsh conditions” and can each store up to 100 terabytes of data through laser inscription, the DARI founder explains.
The Tesseract will be housed in a protected location, with a full-scale replica placed in a major city for public engagement. In addition, “six spacecraft will leave our planet, leave our solar system and carry human memories from the Tesseract into deep into space”, Stojanovic promises. “We’re sending a bold message: It says we were here and we mattered.”
