MIT Press published "Ideas That Created the Future: Classic Papers of Computer Science" in 2021. Lewis edited this 520 page volume. The book collects forty six foundational papers that map the historical development of computer science. The collection spans from Aristotle and Leibniz to Alan Turing and Gordon Moore. Lewis provides a brief essay accompanying each paper to offer historical and intellectual context. The text documents the 1950s Cambrian era of computer design and includes works by Maurice Wilkes, Grace Hopper, and Ivan Sutherland. The book covers theory and practice, architectures and algorithms, and logic and software systems. It includes works by David Hilbert, George Boole, and Whitfield Diffie. Lewis maintained an active presence in academic administration and commentary during this decade. In the spring of 2015 he served as the interim dean of the Harvard School of Engineering and Applied Sciences. He formally retired from his primary faculty position in 2020. Following his retirement he assumed the title of Gordon McKay Research Professor of Computer Science, Emeritus. He continues to teach at Harvard. As of 2024 he instructs Computer Science 1910. The course requires students to read and analyze the classic papers featured in his 2021 MIT Press book. Beyond his books Lewis published several articles analyzing higher education policies. The James G. Martin Center for Academic Renewal published his review of Anthony Kronman's "The Assault on American Excellence" in October 2019. In June 2021 the same outlet published his analysis of Derek Bok's "Higher Expectations". Harvard Magazine featured his commentary in its July August 2024 print problem. The article "Mechanical Intelligence and Counterfeit Humanity" examines the ethical dimensions of artificial intelligence and the responsibilities of human creators. Lewis writes that an artificial intelligence system cannot be divorced from the judgments of the humans who created it. He questions how computers can be trained to value civilization when humans disagree about what civilization entails. He
