From our paper (w/ @smw.bsky.social and @meredithmeredith.bsky.social) in 2024:
![Constraining the flow of sensitive and personal data from citizens that can enable them to be targeted by adversaries using AI systems is in the national interest. To be effective, such constraints may also need
to extend to models trained on this data. The US’s Executive Order on Preventing Access to Americans’ Bulk Sensitive Personal Data, has already considered explicit restrictions on the transfer and export of
personal data [28]. However, commercially available models trained on such data can enable the insights derived from personal data to be utilized for military capabilities (e.g., targeting) even where the data
itself is restricted from sale. To be effective, restrictions placed on personal data flows would also need to be extended to models trained on that data.
(5) Using foundation models in national security contexts may introduce unique concerns threatening human rights. For example, a government’s ability to train models on citizens’ data obtained through commercial data brokers that would otherwise need a warrant, court order, or subpoena to obtain may allow governments to further exercise coercive powers that are automated through AI decision-making [6]. Such use may subvert due process, exacerbated when inaccurate outputs inflict unjust harms on civilians. Appropriate interventions may include the extension of data minimization principles to include purpose limitations on the collection, processing, and transfer of personal data to third parties for intelligence
purposes [6].](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:uvsuoi63hmxbr35fmozsghpc/bafkreicyejqmvq24lsqoalmllt55c2xzcxw5aq5qkhjlnyn6aqx34agzhq@jpeg)

Neither Signal nor any infrastructure provider we rely on has access to the data--thanks to our end-to-end encryption--so neither us nor them can be compelled to hand it over. That's by design.

This is not actually what I said.
What I said is that AI agents, as they're being implemented, particularly at the OS level, threaten the ability of SIgnal and others to provide robust privacy via encryption at the application layer.

I hear you, and thanks! The thing is web clients aren't easy to secure.
However, maybe Signal desktop would be useful to you? You need a mobile account to sign up, but can link it to your Desktop Signal version.

Minder privacy betekent voor bigtechbedrijven vooral: meer data roven waarmee winst gemaakt kan worden. Wat Meredith Whittaker betreft, worden marketingpraat, mythes over superintelligentie en vage privacy-beloften veel te weinig bevraagd. 'Privacy washing in deze branche komt veel voor.'

Engaging in mental gymnastics to justify what's convenient but unevidenced, unjust but personally beneficial, 'rewires your neural map' in ways that degrade your overall ability to understand and analyze the world around you, which is a precondition for intelligence and creativity.

Hey, thanks, and because it appears that the intent of the point re compounding failure didn't come across clearly at least in some corners, I addressed it here. TLDR it's a fundamental tension viz "agency" not an argument that improvements aren't possible

Insofar as agency roughly = the ability to act without explicit checkin and consent, across a series of steps to complete a task.

& yes, deterministic harnesses & checkins are totally possible. But they're in tension w the broader paradigmatic promise of agency.
Or, an agent that checks in on every step (or, whose behavior is deterministically predefined) becomes less and less "an agent."
