To date, no SETI observing program has succeeded in detecting any unambiguous evidence of an extraterrestrial technology. Regrettably, this paper will therefore not dazzle you with the analysis of the contents of any interstellar messages. However, as is appropriate for a plenary presentation, this paper does provide an update on the state of SETI programs worldwide. It discusses the various “flavors” of observational SETI projects currently on the air, plans for future instrumentation, recent attempts to proactively plan for success, and the prospects for future public/private partnerships to fund these efforts. The paper concludes with some tentative responses to the “What if everybody is listening, and nobody is transmitting?” query.
