In any case, heads up displays are coming, a lot sooner than brain implants. In the not so distant future, geotagging and HUDs will match up to create “enhanced reality” (vs. virtual reality), information displayed overlayed on reality. Imagine walking in London with “Snooty Brit’s Guide to Important Places” hooked in to your sunglasses and GPS, so that when you look around, you see Snooty’s notes on real objects.
