Why we cannot wait for better post-quantum signature algorithms

**Executive summary:** This blog post analyzes the current landscape of post-quantum signature algorithms (including ML-DSA, FN-DSA, SQIsign, multivariate schemes like UOV/MAYO/SNOVA, hash-based schemes, HAWK, proof-of-knowledge schemes FAEST/MQOM/SDitH, and others), comparing sizes, performance, security concerns, implementation sharp edges (timing, floating-point, statefulness), and probable standardization/deployment timelines; it concludes none of the new signatures will be widely available in time for the initial PQ migration and recommends migrating now using available options while planning for later adoption of improved schemes.
