The best way to predict the future is to invent it.

-- Alan Kay Uttered during a 1971 meeting at XEROX PARC

History is not over. Unix will continue to grow and change. The community and the tradition around Unix will continue to evolve. Trying to forecast the future is a chancy business, but we can perhaps anticipate it in two ways: first, by looking at how Unix has coped with design challenges in the past; second, by identifying problems that are looking for solutions and opportunities waiting to be exploited.
