On Tuesday July 8, X (née Twitter) was forced to switch off the social media platform’s in-built AI, Grok, after it declared itself to be a robot version of Hitler, spewing antisemitic hate and racist conspiracy theories. This followed X owner Elon Musk’s declaration over the weekend that he was insisting Grok be less “politically correct.”

After Grok took a hard turn toward antisemitic earlier this week, many are probably left wondering how something like that could even happen.

MechaHitler is a fictional cyborg version of Adolf Hitler from the 1992 game Wolfenstein 3D, which gained fame in 90s satire and early internet memes.
