ABSTRACT
<p>Can the 20th-century trend of exponentially improving computer technology be maintained throughout the 21st century? Our best present-day understanding of physics suggests not. Many of the fundamental limits on information processing from thermodynamics, relativity, and quantum mechanics are only a few decades away. Novel physically motivated computing paradigms such as reversible computing and quantum computing may help in certain ways, but even they remain subject to some basic limits.</p>
