Wearable Tech

January 9, 2026, 3:42 AM EST. Nvidia unveiled Alpameo, a reasoning layer for its autonomous-driving stack, at CES, arguing it lets the car explain its decisions. Proponents say it improves handling of edge cases, such as a traffic signal being out, by showing the system's logic. Tesla relies on an end-to-end neural network trained on millions of hours of video, a black box that operators cannot inspect in detail. Elon Musk said Tesla has its own reasoning, but details remain opaque. The debate pits a transparent, reasoning-based approach against a leaner, perception-first design. Industry observers see two paths: high-compute systems that tackle rare scenarios, versus scalable, lower-cost architectures that prioritize speed and breadth.
