  The future of human computation (HC) benefits from examining tasks that
agents already perform and designing environments to give those tasks
computational significance. We call this natural human computation (NHC). We
consider the possible future of NHC through the lens of Swarm!, an application
under development for Google Glass. Swarm! motivates users to compute the
solutions to a class of economic optimization problems by engaging the
attention dynamics of crowds. We argue that anticipating and managing economies
of attention provides one of the most tantalizing future applications for NHC.
