X account @noahcitron posted: “anyone else occasionally get put into an a/b test on a site you normally use where it seems some pm has decided to see how bad they can possibly make the app?”

X account @noahcitron posted: “Probably the most important point here. Hashing is more conservative than EC from the perspective of a quantum adversary. For an AI adversary with only classical computers, we have no intuition that hashes are any better. Similar point can be made for hashes vs lattices too.”
X account @noahcitron posted: “mathematicians: math is beautiful machines: math is ugly. humans were just only able to find the elegant answers. anyways here's an O(n^1.9992) algorithm for 3SUM.”
X account @noahcitron posted: “Hearing a lot of discourse about removing the sync committee since we can prove full consensus now. I like the idea but please let's wait until we at least have secure zkVMs to do the proving.”
