Surprisingly this is actually rather fitting in terms of time scale. When you consider it took ~10,000 agents 88 hours, or 880,000 hours to solve. That's 14.5 years in agent time of continuous 365/24/7 processing. Of course, humans solve things much more efficiently (and didn't also need the massive pre-training of every expert on the planet for 1,000,000,000 human years equivalent). But yeah, human researchers can solve a problem like this in a decade or so, while sleeping, teaching, traveling, and taking breaks, only working a few hours a day on the idea.
