Emerging scientific frontiers in genome editing and brain - computer interfaces (BCIs) promise unparalleled advancements in human health and cognitive capacities. Genome editing, with its potential to modify genetic sequences, might one day enhance traits including cognitive function. Concurrently, BCIs, enabling direct brain-device interplay, present prospects in cognitive enhancement such as amplified memory or learning rates. Yet, as the horizons of these technologies expand, so too do the ethical quagmires, chiefly, the dual-use dilemma in cognitive warfare. There is potential for these technologies to uplift society, offering enhanced cognitive abilities and a new echelon of human capability.
