See also https://github.com/jj-vcs/jj/wiki/JJ-Con-2025 for a list of all the talks, their slides, and some additional notes. I think the slides are also linked from youtube, but the website definitely has them.

I find it interesting that the video itself is unlisted.

So do they want people to watch this or not?

It's Google. They are professional foot-shooters when it comes to making their offerings accessible to their audience.

Shame that Google can't afford anything more than a potato microphone...

Thanks for this!
