Google just moved up their quantum threat timeline - we're looking at PQC migration needs hitting earlier than their original 2029 estimate. The trigger? Faster-than-expected progress in three critical areas: quantum hardware development, error correction algorithms, and factoring resource optimization.

The Bitcoin network remains secure due to its specific cryptographic implementation (SHA-256 + RIPESHA for addresses), but nearly every other system relying on RSA, ECC, or Diffie-Hellman is in the blast radius. We're talking TLS certificates, SSH keys, VPN tunnels, code signing - the entire PKI infrastructure.

The clock is ticking on migrating to NIST's approved PQC algorithms (CRYSTALS-Kyber for key exchange, CRYSTALS-Dilithium for signatures). If you're running any production system with long-term data sensitivity, your migration roadmap should already be drafted. Quantum computers don't need to be commercially available to break your encryption - they just need to exist long enough to decrypt stored traffic.
