For an example of where this already happened, look at the number of people who literally don't have a minor inkling of how to plan a route or navigate without a GPS and mapping software. Sure, having a real-time data source is nice for avoiding construction/traffic, and I'd use a real-time map, but going beyond that to be spoon fed your next action over and over leads to dependency.
More or less at the same time I found “Human Being: Reclaim 12 Vital Skills We’re Losing to Technology”, and the chapter on navigation hit me so hard I put the book down and refused to read any more until my navigation skills improved.
They're quite good now. I sit at the toilet staring at the map of my city, which I now know quite well. No longer navigate with my phone.
I'm scared about the chapter on communication, which I'm going through right now.
I do think we're losing those skills, and offloading more thinking to technology will further erode your own abilities. Perhaps you think you'll spend more time in high-cognition activities, but will you? Will all of us?
