''In 2018, at the age of 83, Dave moved to Japan to become Distinguished
Professor at Keio University and Co-Director of the Keio Cyber Civilization
Research Center (CCRC). He loved teaching, and taught his final class on
January 22, 2026.
At CCRC, one of his most enjoyable activities was co-hosting the IP-Asia

has addressed many aspects of the impact of technology on civilization.''
