In the ever-evolving landscape of technology, the convergence of human intelligence with artificial intelligence has led to the emergence of augmented intelligence (AI). Augmented intelligence aims not to replace human cognition but to enhance it, pushing the boundaries of what the human mind can achieve. One of the most promising frontiers of augmented intelligence is cognitive enhancement, where emerging technologies such as brain-computer interfaces (BCIs) and neurostimulation hold the key to unlocking new levels of cognitive performance.
