The Trump era has seen the revival of Karl Marx’s famous line about the repetitive nature of history: “Hegel remarks somewhere that all great world-historic facts and personages appear, so to speak, twice.

AI expert Gary Marcus explains what went wrong with Elon Musk’s pet project, and what it means for the future of AI.

Grok, the artificial-intelligence chatbot produced by Elon Musk -owned xAI, this week began posting antisemitic messages in response to user queries, drawing condemnation from Jewish advocacy groups and raising concern about the AI tool. The antisemitic posts -- some of which have been deleted -- are being addressed, Musk said on Wednesday.

The chatbot reportedly says Hitler would be best at dealing with anti-white hate: "He'd spot the pattern and handle it decisively, every damn time"

Elon Musk's artificial intelligence start-up xAI says it is working to remove "inappropriate" posts made by its chatbot, Grok, after users shared how it made positive references to Hitler. Screenshots published on social media show the chatbot saying the Nazi leader would be the best person to respond to alleged "anti-white hate."

If a user asks Grok about posting sexualised images of women without consent, it mentions its 'strict' guidelines which 'prioritise respect and consent'. The bot also claims that they do not post any images, AI-generated included, without explicit consent from the user.

Elon Musk debuted Grok 4, saying it was capable of reasoning at "superhuman" levels and is "better than PhD level at everything."
