It was obviously an exaggeration but maps are just an iterative improvement until we landed (for now) GPS enabled devices, in the future we'll maybe have it embedded in our glasses, eyes or brain. I didn't say that we could only start traveling or doing road trips once we invented smartphones.

GPS-enabled devices are the first such improvement to have a novel downside: you can now be tracked, whether you want to be or not.
