Computing has scaled in three ways: algorithmically, through better methods; vertically, through more powerful machines; and horizontally, by connecting machines into larger systems.
Networks made that third dimension possible for classical computing. But the endpoints are changing. They think, entangle, move, and fluctuate.
Each frontier explores a different form of computation. Each raises the same larger question: what does it take to scale beyond the individual node?
Computing has scaled algorithmically through better methods, vertically through more capable machines, and horizontally through networks that make multiple machines work as one. That third axis now grows more demanding: the endpoints can think, entangle, move, and fluctuate. These four frontiers ask what it takes to coordinate richer forms of computation beyond one node.
