LET’S JUST GET the weird part out of the way: I’m typing these words on an invisible computer. Well, kind of. There’s a visible laptop open on the corner of my desk, but only so my (also not invisible) keyboard and mouse can plug into it. But the window containing these actual words I’m writing? That’s just hovering in midair, directly in front of my face, equidistant between me and the now-dark, real monitor I usually use at work.
