Of course it’s not gone, although I suspect there’s a very large number of people who would be surprised to learn either that their Wi-Fi network at home is actually a LAN or that a LAN has utility outside of just providing access to the Internet.
My thoughts after reading the article is that the author compares learning networks and computers isolated on a LAN vs. in the modern world of connected SaaS and the like. That the subject matter is different, less exciting.
It's like comparing a company in its startup phase to its soulless corporate behemoth phase.
And, it's a tailscale blog so it segues to their business.
