MIT Technology Review

MIT Technology Review explainer on how brute-force data center scaling is hitting ceilings as classic scaling laws (Moore's, Dennard's, Koomey's, Kryder's, Keck's) slow, and how fundamental physical limits of computing still leave room for progress. Draws on Feynman's 1959 'There's Plenty of Room at the Bottom' lecture to frame the next frontier below today's engineered limits.
