Seriously, who needs to record someone without the knowledge of the person being recorded? That’s a big red flag, a perverted character, there’s no other explanation. Creepy Mark Zuckerberg allowed other creepy characters to share personal moments with him.
Those kinda exist already. Even Realities G2s, for example: no cameras, built in subtitles and live translation and navigation on a discrete minimal display, open source SDK. Expensive and not quite mature, but that’s a perfectly defensible device to be wearing IMO (they do have microphones. So does your phone)
yeah, that was mostly my impression of what exists on the market too
