As a gen-Z denizen, I found it interesting to hear criticisms of the web from an older person's perspective:
* social media as swinging back to the decentralization of Usenets
* the never-resolved tension between a social network's barrier to entry and content quality
* API and Standards obfuscation by centralized web giants
* talent capture by giant companies
Also, I never knew such a thing as Multics existed. Unix is all I ever knew.
