I will review several trends which will shape both theoretical and observational astronomy over the next five years. First will be the complete conversion of computing to architectures based on market driven microprocessors. Desktops, local facilities, and high end centers will have machines built around either RISC or Intel microprocessors, increasingly using commercial operating systems such as NT and flavors of UNIX (including Linux). Second, web based interfaces to both multimedia datasets and to computing programs will emerge as the universal standard. Third, object languages will be used more often for scientific computing, particularly C++ (as used in AIPS++) and Java. Finally, remote observing, computing, and collaboration will become more common and more integrated as the National Technology Grid emerges from the current Web and Internet.
