It's "edge" basically in the sense that it's on-the-edge towards the physical world: https://en.wikipedia.org/wiki/Edge_computing
In our case, there's some dumb devices, which wouldn't be able to talk across the internet on their own, so we put Raspberry Pis next to them to hook them up to the internet. In other words, the Raspberry Pis just push network packages through, they're not going to be crunching numbers or whatever.
I mean, for me that does come from a place of appreciating real work. If this post would've been AI-generated, I would not have cared about it at all. But that they built the whole scene in Blender, that makes it cool.
