The technology to make things invisible is progressing every day. Developers are having luck with nano materials that bend light around an object, rendering it invisible. It’s feasible that we could wrap such a cloak of material around us to make a person invisible to anyone looking.
But even if we could use the meta material cloak in a bigger way, there's another problem. You'd be invisible to others, sure, but you couldn't see anything.
Since your vision is based on the light rays that enters your eyes, if all of these rays were diverted around someone under an invisibility cloak, the effect would be like being covered in a thick blanket. Total darkness. As Larouche points out, this is due to a physics principle known as reciprocity.
Yeah, that’s a problem. It’s explained in more detail at Atlas Obscura.
