“@SawyerMerritt @Tesla Lidar and radar reduce safety due to sensor contention. If lidars/radars disagree with cameras, which one wins? This sensor ambiguity causes increased, not decreased, risk. That’s why Waymos can’t drive on highways. We turned off the radars in Teslas to increase safety.”

“Grok 4 is at the point where it essentially never gets math/physics exam questions wrong, unless they are skillfully adversarial. It can identify errors or ambiguities in questions, then fix the error in the question or answer each variant of an ambiguous question. [@deedydas] Insane that Elon Musk has pulled it off again, absolutely crushing the AI wars with Grok 4. Summarizing the core announcements: — Post-training RL spend == pretraining spend — $3/M input told, $15/M output toks, 256k context, price 2x beyond 128k — #1 on Humanity’s Last Exam”
“@DavidDeutschOxf Indeed, yes! Clearly describe the falsehoods and “sly” ambiguities or beat a hasty street, sir.”
“Thoughtful explanation of the Supreme Court’s recent decision regarding ambiguous regulatory authority”
“@cleantechnica Pure vision, especially when using explicit photon count, is much better than radar+vision, as the latter has too much ambiguity – when radar & vision disagree, it is not clear which one to believe”
