Rather off-topic, but the juxtaposition of words in the headline made me think of a potentially actually cool application for 3D AR glasses — visualizing the radio-frequency fields in the surrounding environment, colors mapped to wavelengths, saturation linked to RF strength/amplitude. You could look around the house and see the hot and dead zones for your wifi, how much the microwave leaks, how the broadcast radio and TF filters through the building...

Fun for curiosity, but it could be actually really useful for techs?
