The AI Wearable Ecosystem: Closer than you think. Socially acceptable?

I've been researching how personal AI tech devices are likely to develop. technical capabilities, form factors, privacy and governance issues etc. I think it looks likely that there won't be one 'must have' device, and that there'll be of a wearable ecosystem, with devices for different environments. Glasses: outward and inward cameras, picking up facial expressions, gestures etc. Bone conduction audio. Augmented VR, infrared overlay etc. Cuff/Wristband: beyond a smart watch. sensors picking up finger movements/gestures as input. Haptic actuators giving silent notifications.
