Yes, everything at CERN, at least in the 2000s, was in AFS. Fermilab was also using AFS extensively.
I remember compiling AFS from source for Scientific Linux 3.x because there was a weird bug that didn't let the machines mount AFS when they were integrated with LCG (before it was renamed to WLCG: https://wlcg.web.cern.ch/)
Well I'm 50 but AFS in college was superior to all the NFS and NIS silliness I've put up with at the 8 companies I've worked at since then. I wrote another comment about our Unix groups at work and how we have a setuid root command that we type in our password and it changes our groups dynamically.
I’ve been lucky enough to see in person many of these pieces when they were exhibited in DFJ’s offices in Sand Hill Road (~2017-2018). It’s an extraordinary collection.
I don't know much about Jurvetson (apart from him being a VC) but his passion, enthusiasm, and deep knowledge of each of these items in the video is infectious.
