When consumer-grade EEG devices started popping up a few years back, I was thinking the next step would be that they'd be integrated into headphones. I was assuming it would be a selling point, but never thought it might be a hidden feature for the benefit of the manufacturer/state.

The EEG space hasn't done anything interesting in more than a decade. I almost focused my career in the space when emotiv was first making moves. Out of curiosity, I've popped into a few conferences and they've all been pathetic. Similar to how blockchain was going to be incorporated into everything. A lot of hopeful possibilities wound up as dead ends.

Fifth generation warfare probably doesn't need a mostly useless and high noise-to-signal surveillance method like EEGs.

There's unfortunately only so much you can achieve with scalp-based electrodes. The applications everyone dreams about - like fine BCI or controlling robotic arms - are hard to achieve with signals once they've had to pass through the cranium.
