The notice gives no cause, and earnings are still set for November 17. ## A Chipmaker Loses Its Founder ### Nvidia CEO Jensen Huang resigns, effective immediately Nvidia said Jensen Huang resigned as CEO and board member on November 12. Finance chief Colette Kress is interim CEO, and the board is searching for a permanent one. The company gave no reason. Its earnings report is still set for November 17. **Why it matters:** Nvidia makes the chips behind most AI tools, so a leadership shock matters. The official notice names no cause, so treat explanations in the press as reports, not facts. **What you can do:** Watch the November 17 earnings report for what the interim leaders say about AI chip orders and any change of plans.

It reported partial recovery using an alternate health check, with no final root cause yet. Press reports said Outlook, Teams and Copilot were affected. **Why it matters:** Anything that reads your email stalls when the mail service fails. Keep a backup way to reach key contacts for days like this.

At an AMD event, Anthropic's Tom Brown said Claude helped move its software onto AMD's MI355X chips in about three days. No published test backs the timeline yet, and AMD confirms the partnership only. **Why it matters:** If true, switching chip suppliers gets easier, which could ease Nvidia's grip. For now it is one executive's account, so treat it as a claim.

It can book a table or chase a cable company for you. Plans cost $20 or $100 a month, and free users cannot make calls. Meta has not said whether humans ever join calls. **Why it matters:** Calling is the chore people most want AI to take over. TechCrunch notes some receptionists hang up on AI callers, so results may vary.
