In this episode, we're going deep on Cambridge's nerdiest neighborhood, tracing its history from industrial mecca to biotech playground. Scott Kirsner, longtime Boston Globe tech columnist and co-founder of The Innovation Trail, explains the role of MIT in the area's growth, shoots down some JKF-centric conspiracy mongering, and muses on the future of this riverside boomtown (hint: it might depends on how this whole A.I. thing goes).
