Seven AI founders and researchers name the biggest AI opportunities

A Reddit user reports grid-like texture artifacts on the arms and legs of a LoRA-trained character in ComfyUI, while the face renders cleanly. The issue appears only on the body and in a minority of otherwise near-perfect images.

Reporter Timothy B. Lee walked a $4,000 Chinese-made Unitree quadruped two miles to work in Washington, DC, with battery to spare. On the uphill return at 87°F, it hit 5% battery and 84°C internal temperature and collapsed onto its back.

A r/LocalLLaMA user reports the 3.8-27B model is "absurdly superior" to 3.5/3.6-35B across five replicated applied-science projects, from workflow design to data publishing. The tradeoff: 3x to 4x more total wall time.

A Reddit user posted an AI-generated clip mimicking late-80s/early-90s Tokyo — Crown taxis, salarymen, a green train crossing a bridge — saying it looks convincing until you read the signs, where "none of the japanese makes any sense."
