Consumer brain wave headsets threaten privacy

Commenters framed consumer EEG devices as part of a scramble to collect brain data, raising concerns about its use to train AI without users’ knowledge. One pointed to research on side-channel attacks involving brain-computer interfaces as an older warning about what such signals might reveal. Another went much further, speculating that private companies and government agencies seek mind control and that wealthy tech figures could use it to suppress dissent; this was presented as a fear, not a demonstrated capability. Commenters also debated the headline: one called “The scramble for your brain data” the real title, while another explained that publishers often use an SEO-oriented browser title alongside a different page headline.

Practical frustrations accompanied the broader privacy concerns. One owner said a costly Neurosity Crown headset detected head position but produced no EEG data, and that attempts to reach support went unanswered; another suggested reverse engineering it. A commenter said the experience made them increasingly want to disconnect from modern society, though family obligations made that feel impossible. A separate response jokingly prescribed exhausting manual work and commuting as a cure for sleep problems, rather than buying expensive fitness equipment. The discussion thus ranged from worries about data exploitation and speculative control to mundane questions of device reliability, accountability, and the difficulty of opting out of connected technology.
