#20: He Retires From Full-Time Teaching at MIT in 2002 but Remains Active
In 2002, he formally retired from full-time teaching at the Massachusetts Institute of Technology after nearly five decades. He was granted emeritus status, allowing him to continue research and public engagement without a full teaching load.

Retirement did not slow his output. He continued publishing books, giving interviews, and traveling for lectures. MIT remained closely linked to his name, reflecting the long institutional relationship that began in the 1950s and shaped the field of modern linguistics.
