Beyond Post-Quantum Cryptography: Architecture, Memory, and Governance in the Quantum Era

These interview talking points open on the locks-versus-the-archive fallacy: treating post-quantum cryptography as a software migration does not protect historically stolen data. They state that harvest-now-decrypt-later is already underway, with encrypted enterprise archives being hoarded pending a later break of current encryption, and that security has to move from perimeter defence to data-level resilience so the archive can survive independently of who holds the transient keys. They then describe data-centre speciation into three forms: silicon compute (hot, GPU-dense infrastructure for real-time AI), molecular halls (DNA or synthetic-polymer archives for permanent, zero-power retention), and sovereign caches (geopolitically bound, physically air-gapped, jurisdictionally hardened local vaults).
