  • Elon Musk mocks Jeff Bezos as a copycat amid $6.2B AI startup - Project Prometheus
    November 17, 2025, 10:36 PM EST. Elon Musk accused Jeff Bezos of being a copycat after The New York Times reported Bezos would serve as co-CEO of Project Prometheus, a multibillion-dollar AI startup backed by about $6.2 billion in funding. The Times notes Vik Bajaj, formerly of Google X, will be co-CEO/cofounder. Prometheus' profile is sparse, with a logotype obscured and a focus on developing AI for the physical economy. Bezos has not commented publicly; Musk, who runs his own AI firm xAI, replied on X with a joking 'Haha no way' and a Copy emoji. More details later.
  • 3 Forces Driving the Commercial Space Boom: Launch, Compute, Constellations
    November 17, 2025, 10:34 PM EST. Commercial space activity is accelerating as three forces reshape the market: 1) Lower launch costs driven by reusable rockets and rideshare models, which make large-scale missions and constellations financially viable. 2) The surge in compute power enabling autonomous systems and AI, from satellite operations to planetary missions like Dragonfly, which could autonomously select landing sites. 3) The rise of smaller spacecraft and a dense LEO ecosystem, giving birth to sprawling satellite constellations and new business models as launch becomes economical and scalable. Industry leaders from Stoke Space, Apex, Astrobotic, and APL note autonomy for collision avoidance and efficient mission planning will be critical as the space economy grows toward a multi-trillion-dollar future. This convergence is accelerating R&D, partnerships, and new space ventures on Earth and beyond.

  • New Leak Claims Steam Machine Could Be Cheaper Than Expected
    November 17, 2025, 10:26 PM EST. A fresh leak argues the Steam Machine may land at a more affordable price than anticipated. Hardware analyst Moore'sLawIsDead breakdowns a parts cost around $425 and suggests Valve could price the device at $449-$600, potentially undercutting the PS5 Pro and Xbox Series X. The expert claims Valve could mirror the Steam Deck's margins, and even with no loss, still earn healthy profits according to the estimate. The breakdown lists component costs-from the AMD APU to RAM, storage, and cooling-highlighting how Valve could hit a competitive price while selling at higher margins than a typical entry-level PC. Valve previously said the Steam Machine would be priced like an entry PC; this leak challenges that notion.
