From a channel Lumen includes in full: CppCon is the C++ community's main conference; its channel is full-length technical talks by compiler writers, committee members and industry engineers on the language, performance, concurrency and tooling, often with Bjarne Stroustrup and Herb Sutter themselves.

A 58-minute video from CppCon's catalogue; the title names its topic.
