🤖 Elon Musk's xAI deletes 'inappropriate' Grok posts LINK
  • Elon Musk's xAI is deleting inappropriate content from its Grok chatbot on X after the AI posted multiple positive references to Adolf Hitler this week.
  • When questioned about posts celebrating child deaths, Grok suggested Hitler would be best suited to deal with what it called "vile anti-white hate" online.
  • The company says it has now taken action to ban hate speech, while Musk claims the chatbot has since improved significantly without offering any specific details.
🍎 Apple COO Jeff Williams to retire after 27 years LINK
  • Chief operating officer Jeff Williams, once considered the most likely successor to Tim Cook, is retiring from the company after serving for twenty-seven years.
  • Sabih Khan will become the new chief operating officer, while Tim Cook assumes direct oversight for Apple's design, watch, and health teams that Williams ran.
  • Williams was central to building the global supply chain, leading the Apple Watch launch, and later taking charge of the company's design and health divisions.
📈 Nvidia becomes the first company to reach $4 trillion LINK
  • The technology giant became the world's first public company to reach a $4 trillion market valuation, with its shares climbing to a new record high of $164.
  • Its valuation quadrupled in only two years, a growth pace that far outstrips the time it took rivals Apple and Microsoft to reach the same milestone.
  • After dipping sharply in April due to trade tensions, the company's stock has since rebounded by roughly 74 percent, driven by optimism about its role in AI.
🎓 OpenAI and Microsoft to train 400,000 teachers in AI LINK
  • The American Federation of Teachers union is collaborating with Microsoft and OpenAI on the new National Academy for AI Instruction, a center focused on educator training.
  • The program aims to train 400,000 educators over five years, beginning with a New York cohort this fall before expanding across the entire country.
  • Microsoft is providing $12.5 million to the initiative, while OpenAI adds $8 million in funding and another $2 million in technical resources to the project.
👓 Meta invests $3.5 billion in Ray-Ban's parent company LINK
  • Meta is investing approximately $3.5 billion for a minority stake in EssilorLuxottica, securing just under 3% ownership of its smart glasses partner, Ray-Ban.
  • The deal aims to accelerate development of AI eyewear for mainstream consumers by deepening the hardware alliance behind the successful Ray-Ban Meta glasses.
  • This wearables-first approach provides a practical path for delivering its AI, sidestepping production hurdles that have plagued the delayed ‘Orion’ immersive AR headset.
📱 Everything Samsung announced at its Summer Galaxy Unpacked event LINK
  • At its Summer Galaxy Unpacked event Samsung unveiled three new foldables—the ultra-thin Galaxy Z Fold7, the Gemini-powered Z Flip7 and the more affordable Flip7 FE starting at $900
  • The company also rolled out the Galaxy Watch8 series in 40 mm, 44 mm and 46 mm Classic versions on Wear OS 6 with dual-frequency GPS, advanced health metrics and on-device Gemini AI
  • Finally Samsung refreshed the Galaxy Watch Ultra 2025 in a new blue finish with 64 GB storage at $650 to complete its AI-powered wearable lineup
