Today’s biggest tech story dives deep into the current GPU boom and the complex circular financing underpinning it, as analyzed in a new report spotlighting Nvidia, CoreWeave, and Nebius. While these neoclouds propel rapid AI infrastructure expansion with massive contracted power capacities, they struggle with profitability amid soaring costs and debt. In AI software and coding tools, new maker mindsets surfaced: Terry Tao successfully revived two-decade-old Java applets into modern Javascript using AI coding agents, while Mindwalk debuted as a tool to visualize and replay AI coding sessions on 3D repo maps, enhancing transparency of AI-assisted development. On the hardware front, open-source RISCBoy offers a RISC-V based portable game console, and Ghostel.el arrives with an advanced Emacs terminal emulator powered by modern VT engine libghostty. Meanwhile, Mesh LLM introduces a distributed, privately hosted AI compute mesh promising to break central data center dependency. Other highlights include Reed Jobs ramping up oncology biotech investments leveraging AI, OpenAI shifting AI assistant focus toward family use cases, and a significant new security vulnerability found in Motorola’s MR2600 router.
