OpenAI has launched "ChatGBT Gov," a platform designed for U.S. government agencies to process sensitive data securely. Over 90,000 government employees have already used the tool for tasks like document summarization and code generation. The discussion posits that there has been no true technological innovation since the smartphone, with AI serving as a distraction from this stagnation.

Analysis of over 11,000 Facebook patent applications reveals ambitions to track user activities like walking, cycling, and skiing using smartphone accelerometers. Other patents describe technology to analyze political discourse and estimate locations without using GPS.

T-Mobile's international data roaming and tethering policies are analyzed during a remote broadcast. While the provider offers unlimited worldwide data, high-speed tethering for laptops requires separate data buckets that can reach costs of $50 for 20 gigabytes. The performance of LTE in New York City is noted as sufficient for high-quality audio transmission without significant latency.

LiFi is an emerging technology that uses the rapid flickering of LED lights to transmit data to smartphone cameras. Researchers at Fraunhofer have reportedly achieved speeds of 3 gigabits per second using this method, which offers a localized alternative to traditional radio-frequency Wi-Fi.
