Revolucija silicijske fotonike – tehnologija brzinom svjetlosti koja mijenja AI, podatkovne centre i više

Silicijska fotonika koristi silicijske fotoničke integrirane sklopove (PIC-ove) za manipulaciju svjetlom u svrhu obrade podataka i komunikacije, omogućujući međusobno povezivanje unutar čipa i između čipova brzinama poput 100 Gb/s i 400 Gb/s. Silicijski fotonički čip veličine nokta može sadržavati desetke laserskih kanala

  • Tesla Model 3/Y Batteries: Panasonic NCA Lasts Longer Than LG NCM811, EV Clinic Claims
    December 9, 2025, 12:36 AM EST. EV Clinic, a Croatia-based EV workshop, compared Tesla Model 3/Y battery packs and found clear differences between LG Energy Solution NCM811 packs (Nanjing, China) and Panasonic NCA packs (Made in USA). The report suggests hype around China-made batteries is overstated, with LG packs showing high failure rates and shorter lifespans. In EV Clinic's data, LG packs last about 250,000 kilometres, while Panasonic packs can reach around 400,000 kilometres. In over 90% of customer cases, cell-level repairs on LG packs were not feasible due to multiple cells with high internal resistance and cascading failures; repairs were often uneconomical. Panasonic typically shows only a single cell failure around 250,000 km and is repairable. The conclusions are limited to these specific packs and not a universal claim.
  • ARK Invest and Mach33 Launch Open-Source SpaceX Valuation Model: $2.5T by 2030, $12.5T by 2040
    December 9, 2025, 12:32 AM EST. ARK Invest teams with Mach33 to release an open-source SpaceX valuation model that projects a $2.5 trillion enterprise value by 2030 and up to $12.5 trillion by 2040. The model translates SpaceX's ambitions-from launches to satellite networks-into a transparent framework for evaluating revenue, margins, and long-term growth. Proponents say the open approach could boost investor scrutiny and collaboration around space commerce, launch economics, and risk factors. Critics warn that assumptions around demand, competition, and regulatory risk could swing outcomes, underscoring that the model is a framework, not a guarantee, of future performance.
  • Jamie Dimon on AI's future: fewer jobs and 'working less hard, but having wonderful lives'
    December 9, 2025, 12:28 AM EST. Jamie Dimon discusses how AI and automation could redefine work in the coming years. He suggests smarter machines may reduce repetitive labor, potentially letting people work fewer hours while still earning a good living. The conversation covers new business models, the importance of retraining and education, and policy measures to prevent dislocation. Dimon emphasizes the dual goal of higher productivity and better lives-more time for family, creativity, and community. He warns that benefits depend on smart investment, inclusive growth, and robust safety nets, not just technology. The piece portrays AI as a transformative force for both the economy and everyday life, contingent on policy choices and corporate leadership.
  • Trump clears way for Nvidia H200 exports to China, easing U.S. chip controls
    December 9, 2025, 12:26 AM EST. US President Donald Trump has cleared the way for Nvidia to export its H200 chip to China, easing export controls. Under the arrangement, 25% of sales would go to the US government, with exports limited to "approved customers" and safeguards for national security. The move marks a shift from the Biden administration's tighter policy that confined Nvidia to downgraded Chinese products. Nvidia called it a thoughtful balance that could support American jobs and manufacturing. Markets nudged Nvidia shares higher after hours. Analysts say the policy signals a shift from blocking China's tech progress to competing for market share in AI, potentially accelerating innovation, though it drew swift political backlash.
  • Expert Warns Smartphone Users to Turn These Three Settings Off to Avoid Security Breach
    December 9, 2025, 12:16 AM EST. An expert warns that three common smartphone settings, if left enabled, can substantially raise the risk of a security breach. The article identifies the settings to disable, explains how each one expands the device's attack surface, and outlines practical steps to protect privacy. It also suggests pairing these changes with regular OS updates and mindful app permissions to maintain a safer, more private device experience.
