The social and cognitive differences between the two hominid species, Homo sapiens and Homo neanderthalensis, are described. Based on findings from genomics, neuroscience, archaeology, and paleobiology, it appears possible that the capacities of Homo sapiens could outreach those of AIs in some ways. Especially important are human visuospatial, cultural, and, oddly enough, theological capacities, and the interaction of these capacities in group problem-solving. While communication between AIs is fast and can be widespread, the authors ask whether this is the right kind of communication for solving problems of survival. An important question is explored throughout: Is it ethical to withhold from AIs human-like capacities that may become possible to install? Finally, a worrisome question is broached: Is it the best course to create AIs in our own image to safeguard our existence in unknown future interactions with extraterrestrial species, both organic and inorganic?展开更多
