You know, maybe my grandparents had it right.
It is weird that computers give so little sensory feedback for what they're doing. Flashlights go click. Cassette decks go clack-vrrrr. Whiteboards go squeek-squeek. Screen sharing goes... nothing, just a small mostly white rectangle on top of my much bigger rectangle until a disembodied, 4 kHz-wide simulacrum of someone's voice from halfway around the world says "yeah we see your screen". Unnatural is what it is.
