Build consumer AI assistants that combine user‑held cryptographic keys (passkeys) with server‑side trusted execution environments (TEEs) and publicly auditable attestation logs so that conversational data is technically inaccessible to platform operators, third‑party vendors and casual subpoenas. The stack is open‑source, includes remote‑attestation proofs and public transparency logs to enable independent verification and forensics without exposing raw content.
— If adopted, attestation‑based assistants could force a fresh legal and technical fight over who controls conversational data, reshape law‑enforcement preservation/court‑order practice, and create a new privacy standard for consumer AI.

The Perplexity lawsuit alleges its Incognito mode did not prevent sharing conversations and identifiers with Google and Meta, directly illustrating the problem that 'attestation' (technical and legal guarantees about an assistant's data practices) is meant to solve—i.e., consumers and regulators need verifiable claims about where assistant data goes.

The article reports Intel's Heracles FHE accelerator (3 nm, HBM, liquid‑cooled) achieving up to 5,000× speedups on encrypted queries (voter verification demo). That concrete hardware advance directly supports the feasibility of 'attested' or privacy‑preserving AI assistants that can compute on user data without seeing plaintext, reducing the technical barrier named in the existing idea.
