Kaku: How Advanced Could They Be?

Astrobiology Magazine has an interview with cosmologist Michio Kaku, who considers the physics of extraterrestrial civilizations and whether we can predict their evolution from our own. Strange, in an article that screams for a discussion of the Fermi Paradox, Kaku manages to avoid it completely. He also avoids any discussion of artificial superintelligence and Drexlerian nanotechnology -- although he does discuss Von Neumann probes and Kardashev civ types.
