Game Not Over
archive.org has good newsletter and the newest edition contained a link to the video of their Game Not Over - virtual event, which I really recommend to watch.
They have a fun and interesting chat with John Carmack after which they have a panel discussion. Topics which are touched in the first 30 minutes: open source, Wolfenstein 3D, Doom, Quake and “Hackers - Heroes of the Computer Revolution”.
