Maybe you’re right. As the general population uses less and less of their creative brains at some point they will be incapable of coming up with an alternative to gps (today someone would most likely have the cognitive capability to erect positioning beacons on their farm).

It isn't just making an alternative, it is rolling it out as well.

> We can't grow enough food to support our population without GPS

Can you justify this?

Edit: I mean can you provide an authoritative source or a plausible argument for believing this?

GPS allows significantly more crop to be grown on the same land. By giving plants the ideal spacing they harvest the amount of light they need without shading each other or letting light fall unused on the ground (or on weeds that in turn shade the plants). GPS also starts/stops each row of your planter as you cross already planted areas of the field, thus saving a lot of seed and in turn leaving more land free to grow crop instead of seed. GPS also always fertilizer to be placed where needed thus not over fertilizing some areas while under fertilizing others.

So far so good, but none of that answers my question.
