Why for Homo sapiens to become Homo deus, it must stop to be Homo stupidus? All my conscious life I have been studying intelligence, as "the power/ability/capacity to know and learn, understand and infer, decide and effectively interact with the world, at all its forms and levels". The latent variables describes unobservable aspects of reality, physical, mental, social or digital. They could relate to abstract entities, like real-world/ontological categories and classes, mentality or machine intelligence, or data structures. In human intelligence, the underlying causes of the observed variables is the g factor (general intelligence, general mental/cognitive ability or general intelligence factor), computed by the IQ.
