Pushing them faster also bumps seniors who were looking forward to their up against thermal issues as the predicted last semesters at Cornell. temperatures on-chip become comparable I recognize that these are difficult to that of a rocket nozzle. times and many uncertainties remain, Does that mean the end of innovation very nature of computation by building but I sincerely believe that by working in electronics? No, it’s just the beginning. memory devices, algorithms, circuits, and together as a community, we will achieve Instead of investing in manufacturing devices that directly integrate computation the best possible results for the health and that matches the pace of Moore’s law, even at the cellular level.

Although we major manufacturers have realized highlighted in this issue is exciting in that are distant from each other, our work in that it is cost effective to pursue other it breaks the traditional separation between ECE continues. approaches such as graphics processors, switches and gates, between memory and Around 1965 Gordon Moore, the innovative computing architectures, novel computing functions, all the way down to co-founder of Intel, predicted exponential devices, new materials, hybrid chips, AI, the device level. increases in computer performance which and quantum computing.
