Some "AI" on my phone is reading inbound Signal messages. I left predictive typing on, trading a little of my privacy for convenience. Yet something is giving responses using what others wrote in chats with disappearing messages, persisting or sharing them who knows where. Not a good default, Google

We've crossed a threshold. A paid subscription used to be the ultimate proof of humanity online, now its not enough to allow a single link click inside the NYT cooking app. The next few years are going to be an interesting race to extract more and more invasive proofs of humanity.

Making LLM chats private is a good idea. We've accepted too much data harvesting already—this moment lets us reset the norm around who controls our data online. But let's go further: put LLM chats in private compute, so you get technical guarantees you control your data.

Classic Google: an A/B test (a rare overt one)
Classic Google AI: it doesn't actually work (you can't submit)

Incidentally, if your Signal is now flooded with work chats, you can organize chats into folders
Settings->Chats->Chat Folders. Looks like its Android only for now.

@meredithmeredith.bsky.social points out the real story with Apple disabling encrypted backup (and therefore effectively iMessage encryption) in the UK. The UK is demanding a global backdoor for all data, including Americans. Apple is resisting as best they can.
