Sitting in a bustling café in Berlin, I overheard a heated conversation between two tech enthusiasts discussing the potential of brain-computer interfaces. One argued that such technology could unlock unprecedented cognitive abilities, while the other dismissed it as science fiction. As I sipped my cortado, the contrast between their opinions made me wonder: what if the future of our brains included direct communication with technology? Could brain chips, once the domain of dystopian narratives, be a force for good in human evolution?
