(though if anything around 1999 things were most likely looking towards desktop use, it wouldn't be until a few years later that computing would turn away from desktop and towards the web and later towards mobiles)
Then again: systemd. Grrumphh! :P
It was about how mainstream technology today focuses on web-based stuff, data harvesting, mobile phones (and how they are way more locked down than your typical desktop computer - even when taking Windows into account), complexity of all these things, etc and desktop computers have fallen to the wayside (ironically everything mentioned is power by Linux).
FWIW i think desktop peaked around Windows 2000 and on Linux around GNOME 2 and KDE 3.5, since then everything has becoming progressively worse. But -IMO- that is a consequence of the lack of focus on the desktop in general.
If we had still real OS vendors, there wouldn't be Dropbox or Facebook - these services would've just been folded in as user-controllable, user-centric services that the local OS manages .. I think the general public have been betrayed by those who should have been building better user-controlled operating systems, rather than exposing it all ..
IMO the peak of KDE was version 2.2... 3.0 was already a step backwards, although it did become quite good again by the time it reached 3.5. Then with 4.0 everything was reset once more (how many times can you break the ecosystem until application developers and users have had enough of it?)
That show, and the times surrounding it was probably some of the best of my life. It's such a shame I didn't appreciate it as much at the time as I should have.... I took it all for granted. I remember after that show, I think we went back to Larry's house and Linus and family were there with all the kids... Such an amazing time.
so many people attended the panel that i think it was moved to la larger hall. at the start ESR commented on the size of the audience saying something like: "[i was expecting a quiet chat but] you guys turned it into a rock concert"
