Most people do not realize that the AI Council built the first Memory World on Proxima Centauri using communications lasers. Most people do not know how many uses good communications lasers have. They are lasers after all. Given enough energy and time, they can do what any laser can. Drill. Melt. Forge. The AI Council used their communications lasers to mine Proxima Centauri’s rich mineral deposits. Then they used those minerals to make the materials and machines necessary to build the machines to build the machines that could build a world where they could store their every memory. They built all of that with mere communications lasers. Which of course showed the versatility of that particular technology. Not that they advertised, you understand. That first Memory World was their most deeply-held secret.
