Along with @rjdrost, @NamikMuduroglu, we spent the past two months writing this position paper megaeth.systems/revisitworld… with comments and feedbacks from @VitalikButerin, @sreeramkannan, @post_polar_, @Austin_Federa, and @0xMegaMafia. Personal computers empower individuals to process an almost-infinite amount of information. The Internet empowers individuals to cast their thoughts throughout almost the entire world. However, these technologies have not fundamentally changed how individuals form societies––a process that depends on trust, delegation, and sometimes, exploitation. What we need is a steward that faithfully enforces every invariant in interpersonal and intermachine coordination––a World Computer that, by design, is correct, open, responsive, and capacious. With recent advancements in theory and engineering of distributed systems, a World Computer whose efficiency approaches the physical limit is now within our reach. The World Computer is not just a vision; it is a call to action. It is time to let loose your imagination and build!
