NVIDIA SEEKS TO MAKE HUMANOID AI ROBOTS SAFER AROUND HUMANS

Nvidia has created a lab where robot makers and customers can run safety tests before going to regulators to receive the necessary certifications. Engineers at the lab can help with pre-inspection work and engineering tweaks as needed. Robot safety design is much more complicated than safety design for autonomous vehicles, which generally just involves avoiding contact with people and other objects. Robots need to be able to know what things they can or can't touch, move, or exert force on.

JOHN TERNUS SET TO RE-ESTABLISH IMPORTANCE OF APPLE'S DESIGN TEAM WHEN HE TAKES OVER AS CEO

Apple is reportedly preparing for a shift back toward design-led product development under incoming CEO John Ternus, after years in which operations and finance gained greater influence following the departure of Jony Ive. Ternus has been working closely with Apple's industrial design team and wants to restore its authority, reflecting a philosophy closer to the era when design played a dominant role in shaping Apple's products. He is expected to become the public face of major hardware launches, including Apple's upcoming foldable iPhone, and has emphasized that Apple products should remain among the most beautifully designed items customers own.

THE OPTIMAL AMOUNT OF SLOP IS NON-ZERO

Software requires different levels of verification depending on its use case. Casual software has limited distribution and loose quality constraints. Business software needs to work, or organizations suffer losses. Acute software is mission-critical and merits the highest levels of scrutiny. The amount of permissible AI-slop decreases as the risks of the software failing increase.
