SpaceX Has an AI Device Prototype, Report Says — Then Musk Publicly Denies It
TechCrunch reported July 1 that SpaceX has been developing an AI-focused hardware device that 'sure sounds phone-ish,' citing internal sourcing on a project exploring a Starlink-connected, xAI-powered consumer device. Elon Musk publicly denied the specific report within hours, per The Verge, even as SpaceX's fresh public-market currency (following its roughly $2.1 trillion day-one IPO valuation) and its $60 billion all-stock acquisition of Cursor make a hardware-plus-AI push entirely plausible.

SoftBank's CEO Isn't Alone in Doubting Elon Musk's Orbital Data Center Hype
As Elon Musk pitches data centers in orbit to power the next wave of AI compute, skepticism is mounting -- and SoftBank's Masayoshi Son, himself one of AI's biggest spenders, is among the doubters. Critics question the physics, economics and cooling realities of running AI clusters in space, casting the idea as visionary marketing more than near-term infrastructure.

'xAI Is a Failure': A Leading AI Researcher Calls Out Musk's Lab
One of the field's most influential researchers publicly argued that xAI has failed to become the frontier challenger Elon Musk promised three years ago, as OpenAI, Anthropic, and Google pull further ahead on both models and revenue. The critique lands as Musk's attention -- and SpaceX's newly public balance sheet -- sits elsewhere.
