Unless we're dumping on X and Musk (and we absolutely should be), the "Nazi AI" is a footnote. The headline is "LLMs are trivially manipulated by an unseen hand that can change how responses work after testing and promoting an app to prod and there's nothing you can do to mitigate this." 2/

3/ Yes, John Nunn IS one of my #chess favorites, but 1001 Deadly Checkmates is excellent in every way: real, well-organized positions ranging from easy (but not absolutely basic) to skull-busting, and a scoring system for data tracking nerds like myself. All #chesspunks should work through this one!

My contempt for anyone involved with this drivel knows few limits. Conflating issues and fear mongering because a Chinese company dared to publish an actual open model:

Hypocrisy, lies, grifting :-(
