The existence of intelligent extraterrestrial life forms among the thousands of billions of galaxies that dance in the Universe is beyond doubt (1). Meeting with one of them is only a matter of time. SETI (Search for Extraterrestrial Intelligence) has been searching for them for only half a century. However, the crucial question today is whether we will have time to establish contact given the multiple threats that humanity puts on itself. Therefore, it seems urgent to launch a program complementary to SETI which could be called STI (Search for Terrestrial Intelligence).
