đź’¬ Key Insights
"The question isn't whether we have AI governance, but whether we develop it thoughtfully today or reactively tomorrow. SB 53 offers a solid path toward the former."
"One of the biggest problems in robotics is that we don't have enough data...Having the self-improvement aspect is almost like simplified reinforcement learning without needing to do reinforcement learning fully"
"The self-improving part here is that after you do pre-training in stage two, you can do online self-improvement with on-policy rollouts of a robot...you're basically able to generate a continuous stream of success and failure rollouts"
"Their way of getting to better results isn't just by increasing parameters. They're actually thinking about scaling and using planning before you think, prompt restructuring."
"Tesla's robotaxi is planning to test in Nevada...but there was reporting from Electric about there already being three robotaxi accidents, with at least one injury reported...the NHSTA is investigating Tesla for potentially misreporting the crash data."
"It's very tricky for these companies when they try to avoid or hide these accidents. That was really what got Cruise in trouble in San Francisco"
