1. The document discusses how real-time communications (RTC) technologies like WebRTC have become increasingly important during the COVID-19 pandemic for allowing shared virtual presence online. 2. The W3C is working to standardize WebRTC and adapt it to new usages arising from the pandemic through their WebRTC working group, prioritizing features like seamless screen sharing. 3. The talk describes designing the future of RTC to make online interactions more personal and intimate through technologies like higher fidelity video and new encoding techniques.
