Going through some Erdős problems that Mark Sellke and Mehtaab Sawhney found had already been solved using GPT5 pro for search. More precisely, these were listed as open, but solutions to them already existed in the literature, but not recognized as such. Quite remarkable.

Behold the striking colors of the blue-spotted stingray! Its bright spots are a warning to onlookers that it's venomous—& if its colors aren’t enough to ward off foes, it’s equipped w/ a tail that can inject a lethal dose of toxins.

The Royal Game of Ur is the world’s oldest playable boardgame!
Played by Sumerians in ancient Mesopotamia about 4,500 years ago!
It is a two-player race game, the rules of which have been deciphered from a cuneiform tablet.

I don’t think the main character in Friendship was a narcissist. I think he was deeply burying his grief, protecting himself, and ruining everyone else’s lives in the process.

#sftechweek requires events to be on partiful, and only partiful. SF event spaces are usually only reserve-able via luma.
this has led to all kinds of chaos.
