Some of my coworkers were talking about using RSS to read blogs, which made some of the younger folks in our team ask what it is and why we keep using it.
Some still use iPods to avoid subscriptions and streaming services, my favorite was one of our sysadmins who showed me Gopher.
I’m curious about others though, thanks!
If we’re talking about technology that is no longer widely used, it’s probably my old HP48SX from the early 90s. Still use it sometimes as a desk calculator, though I have an HP48GX emulator app on my phone as well. Gotta have my RPN.
