Human minds have hit an evolutionary "sweet spot" and -- unlike computers -- cannot continually get smarter without trade-offs elsewhere, according to research by the University of Warwick.

For instance, among individuals with enhanced cognitive abilities- such as savants, people with photographic memories, and even genetically segregated populations of individuals with above average IQ, these individuals often suffer from related disorders, such as autism, debilitating synaesthesia and neural disorders linked with enhanced brain growth.
