Unfortunately you probably daily rely on multiple 32-bit linux machines, most of the time not realizing you do. I agree this should be mentioned in the title though.
I was feeling the same, about the only thing I have using 32bit userspace these days are a few rPIs, little bit early to be panicking they may suffer from the Y2038 bug, most companies waited to about 6 months before the Y2K bug was going to hit before they started caring.

Quite the opposite if you're talking about rPIs: the small/embedded space is where things can live for a long time. They're the primary place to worrying about. Especially if you're talking about industrial processes.
