While it may be an exaggeration to say that orthodox Objectivism, since ARI continues to exists and apologists for that organization still exist. But as an intellectual force, it is dead --- and probably not revivable. Some might argue it's been dead, or close to death, for several decades. But there was always a hope, however dim and unlikely, that the corpse might be resusitated. Indeed, in 2008, orthodox Objectivism showed a brief flicker of life. Sales of Atlas Shrugged surged, and Rand once again became a favorite target of the left. But in the end, nothing came of it. In 2010, Leonard Peikoff conspired with ARI executive director Yaron Brook to force John McCaskey, a lucrative donor, to resign from the ARI board of directors for the sin of challenging then Peikoff protege, David Harriman. In retrospect, that unsavory episode appears to have been orthodox Objectivism's last gasp. While ARI will undoubtedly persist for many decades to come, perhaps even longer, in terms of intellectual significance, it's impact on the culture will be so close to zero that it might as well be zero.
