I have no faith in humanity, especially those involved in tech, to make this. If they did, they'd block real life marketing only so it could be used to replace with ads bought directly with the AR maker.
If we had good AR hardware, I bet this would eventually get made, just not by big tech. It would be a third-party, probably open source mod that uses the optics of a corporate device to run their own software. It would be unwieldy, expensive and janky, but so worth it. I wonder if the advertising industry would try to get it outlawed if this happens.
When I first saw Google Glass this was my exact idea for the perfect use case. It's a shame that the advertising-fueled, spyware creeper reality of the tech makes that dream seem ever distant.
Seems like a good feature for AirPods too, though the new CEO Ternus seems committed to the opposite.
