Elon Musk said he's open to assisting Apple in upgrading its virtual assistant 'Siri' using his company's AI model Grok 4.1. A social media user's post suggesting that Apple should dump Siri's "outdated" tech and replace it with xAI's Grok 4.1 went viral on X. Musk responded to the post saying, "I'm down." Apple hasn't said anything about the exchange.
