Astronomy and astrophysics is only exceeded by Earth and Environmental Sciences as a driver of change in high performance computing and communications. The need for realistic simulations of nature, as shown in the morning sessions, push supercomputer centers to move aggressively toward teraflop computational speeds and terabyte computer memories. Observational astronomy is pioneering the notion of distributed digital libraries and data archives as well as remote real-time control of observatories over the internet or gigabit testbeds. Using information browsers such as NCSA Mosaic, allows an international instantaneous sharing of information about all aspects of our discipline. Taken together, these trends give us a glimpse of what a digital astronomy will be like in the next century.
