For what it's worth, a Google search for
"io" "linux"
has "io GNU/Linux" as its first hit, but that's the name of a distribution, so I'm not sure it counts. The second hit is "Linux server performance: Is disk I/O slowing your application?":
https://haydenjames.io/linux-server-performance-disk-io-slowing-application/
but the next two are "How can I monitor disk io?"
https://unix.stackexchange.com/questions/55212/how-can-i-monitor-disk-io
and "How to Monitor Disk IO in Linux":
https://www.linux.com/learn/how-monitor-disk-io-linux
And, as per my comment about old people, a Google search for
"io" "z/os"
(that being an OS descended from one in use at the time when I first heard of "I/O") has "I/O" as the term in the top two hits.
