At least all the things NSA and CIA are interested at the time…

All new things always have an intelligence aspect to it:

• Find my network: Find any device globally by its ”anonymized” identifier. Make a device you hack remotely send these BLE pings and voilà, some Apple or Google device is surely nearby to hear it and tell you where it is.
• Voice assistants: Hear what people talk about privately by injecting new wake-up words like ”Trump”. Cannot be used en masse yet perhaps because it’s usually only the device detecting the trigger word, and sending ”uncertain interpretations” too often would get noticed by someone.
• LLM chats: Well the same as Google searches etc. historically but now way more nuanced and with more context of what the target in intending/thinking. Building a psychological profile of them through features like ”memory”. And as LLM is such an undeterministic black box, you can easily get away with injecting all sorts of ideas through its responces.
