The article provides ancillary hyperlinks to nearly every topic mentioned, but fails to link the actual video of Kernighan speaking. Here it is: https://www.youtube.com/watch?v=WEb_YL1K1Qg

In reality the subject of the talk is Kernighan’s perspective of the history of Unix at Bell Labs. The questions covered in the article are the least interesting part, and make up about six minutes at the very end—a small fraction not just of the 70-minute video, but even of the 30-minute Q&A session.

In short, the headline and article are disappointing clickbait, but the video itself is worth watching for Kernighan’s relating of history and his theories about what confluence of factors made Unix successful (collegial environment, good management, overall mission…).

Another worthwhile video from the same conference (in a different year) is Kernighan’s interview of Ken Thompson: https://www.youtube.com/watch?v=EY6q5dv_B-o&pp=ygUSdmNmIGVhc...
