Amazon-acquired Bee wearable captures 10M tokens/year with zero-access encryption architecture

“you can learn virtually everything about the person within the just like one week of wearing the B device which is extremely sensitive”

Bee, acquired by Amazon ~8 months ago, built an AI wearable that continuously records audio and constructs a personal agent on ~10M tokens of annual per-user data — with a zero-knowledge architecture that prevents even Amazon employees from accessing the data. The engineering insight is their shift away from request-response LLM patterns toward a persistent stateful runtime that runs continuously without requiring the user's device to be online. This foreshadows an emerging architectural paradigm for always-on personal agents that mirrors how cloud code agents now run for hours rather than seconds.
