Mike Frank: even O(n log n) multiplication isn't practical, new results won't be either

Mike Frank comments on the latest big-integer multiplication complexity results (claims pushing the log n exponent to 0.9999). He notes that even the O(n log n) multiplication algorithm isn't really useful in practice, so he'd be very surprised if these asymptotic breakthroughs have any practical relevance at all — a sober take on the gap between theoretical complexity records and real-world utility.
