Live Science Today: Jensen Huang AGI Claim and Major Leap to Reanimation After Death
Nvidia CEO Jensen Huang announced on the Lex Fridman podcast that humanity has already reached artificial general intelligence, citing recent advances in large language models and the OpenClaw platform. He later qualified his claim, acknowledging that the probability of 100,000 OpenClaw agents building Nvidia is effectively zero. In unrelated biotech news, a team reported successfully cryopreserving a pig’s brain with minimal damage, preserving neurons, synapses and molecular structures. While the preservation technique marks a milestone, experts caution it is closer to high‑fidelity embalming than a viable path to reanimation.
