American economist Robin Hanson introduced the “Great Filter” concept in an article titled “The Great Filter- Are We Almost Past It?” published in 1996 [209]. The concept of the Great Filter suggests that extraterrestrial civilizations may never reach a stage where they can colonize their galaxy and be detectable because they encounter obstacles or setbacks that impede their technological progress or lead to their early demise. This idea posits a fundamental challenge that all intelligent life forms will likely face at some point in their development. The existence of such a filter could explain why we have not yet found any signs of extraterrestrial civilizations.
