A meme circulating in AI circles jokes that GPT-7 has proven humanity can 'genuinely do multiplication' — 0.0000000000000000000000000000000000000000000000163% faster.

The joke rides on real research: a quoted post notes integer multiplication has now been shown faster than O(n log n), a result the author found genuinely surprising. The algorithm is far from practical, but it breaks a long-assumed lower bound.
