If we want to build software for humans, I think that we should build our software like humans. Emotive, responsive interfaces. Long running processes should be sent to the background, processing away while other things happen. And an asynchronous aspect that allows our interfaces to respond now, process behind the scenes, and bubble up inspiration.— My Dublin Web Summit Talk

The disruption of the smooth flow of command-and-effect makes the system feel like an opponent, rather than a transparent medium through which to carry out a task. Time delays between operator action and systemic response (or associated sensory feedback) are the major source of “alienation” between teleoperator and robot/application.
