    I thought this had to be hyperbole, so I did the math myself. I’m assuming human history is 200,000 years as google says, and we want to narrow this down to the second the bike disappeared. also that the bike instantly vanished so there’s no partially existing bike.

    each operation divides the time left in half, so to get from 200k years (6.311×10^12 seconds) to 1 would take ~42.58 divisions, call it 43. even if we take a minute on average to seek and decide whether the bike is there or not it would still be less than an hour of manual sorting

    hell, at 60fps it would only take another 6 divisions to narrow it down to a single frame, still under an hour

      I regularly bisect commits in the range of 200k (on the low end) for finding causes of bugs. It takes me minutes. Pretty crazy

      History is about 10k years, the 200k years is mostly pre-history. People didn’t write stuff down until they invented agriculture and needed to track trade between owners, workers, etc

      Combine AI image/visual-pattern recognition and quantum computing, and this search could be completed before it was even started.
