Seems like it should be a story? 5758191881

I mean, Erdos problems are cool (I genuinely mean that), I didn't know about the Jacobian conjecture before it got disproved. But this newest batch from OpenAI hits home in a way the previous announcements did not. 232972

Noah Stephens-Davidowitz @noahsd.bsky.social · 07/01/2026I wrote up a little blog post proposing a slightly different way to write asymptotic notation. www.solipsistslog.com/a-simple-and... In short, I think asymptotic notation should usually be written with an INequality. E.g., f(n) <= O(n^2), f(n) < o(log n), f(n) > 2^{-o(n)}, f(n) >= n^{-O(1)}, etc.solipsistslog.comA simple and modest proposal for improving asymptotic notation | Solipsist's Log 5165
