At the intersection of neurotechnology and artificial intelligence, one of the most promising tech frontiers of the next decade is rapidly taking shape. According to Grand View Research, the global market for brain-computer interfaces (BCI) is valued at over $2.4 billion today and projected to grow to $6.5 billion by 2030. Once limited to research labs and clinical institutions, BCIs are now becoming accessible to indie developers, startups, and even hobbyists — thanks to non-invasive EEG headsets, Bluetooth protocols, and open-source machine learning tools.
