Episode notes
Neurotech Is Already Mainstream
- Consumer neurotechnology already exists in rings, watches, earbuds, headbands, and wristbands that pick up brain activity.
- AI can decode those electrical patterns into emotions, attention, and intentions.
Classroom Headsets In China
- Chinese schools reportedly required fifth graders to wear headsets that signaled attention with green, orange, and red lights.
- Students said the data was sent to teachers, parents, and the state and sometimes led to punishment.

- That combination would create deep asymmetries of power and chill workplace autonomy.
