There is a bottom to the hierarchy of conscious agents. At the bottom reside the most elementary agents—“one-bit” agents—having just two experiences and two actions. The dynamics of a one-bit agent, and of interactions between two such agents, can be analyzed completely.23 Here, at the foundation of agents, we can hope to connect with the foundations of spacetime, with physics at the Planck scale, and discern just how agents boot up a spacetime desktop.
