I should have noticed it before, but here am I. At the link above you can read a thought-inspiring blog entry by Helen De Cruz reporting Elizabeth Fricker’s arguments on how we rely on the “testimony” of GPS, googlesearch and so on and have lost the skill to read maps, sum up numbers and so on. This is closely related to a further problem I have dealt with in the past, namely whether thermometers, GPS devices and other tools can be said to be testimony-bearers. You can read more about this controversy at this post (and in the article it refers to).
