This would be like having a smartphone in one’s head, with the ability to call up mountains of data instantly and without ever having to look at a computer screen.The next step might be machines that augment various brain functions.Once scientists complete a detailed map of exactly what different parts of our brain do, they will theoretically be able to augment each function zone by placing tiny computers in these places.For example, machines may allow us to “process” information at exponentially faster speeds or to vividly remember everything or simply to see or hear better.Augments placed in our frontal lobe could, theoretically, make us more creative, give us more (or less) empathy or make us better at mathematics or languages.(For data on whether Americans say they would want to use potential technology that involved a brain-chip implant to improve cognitive abilities, see the accompanying survey, see U.S. Public Wary of Biomedical Technologies to ‘Enhance’ Human Abilities.)Genetic engineering also offers promising possibilities, although there are possible obstacles as well.
