There are several variants of a list in circulation with skills our grandparents could do but the majority of us can't, for instance, 7 skills your grandparents had and you don't. Examples include ironing really well, sewing, knitting, crocheting, canning, cooking a meal from scratch, writing in beautiful longhand, basic DIY skills... What have the majority of us lost by not having these skills, which I'll call granparent skills for short, anymore?
As Lizzie Fricker argued today in a workshop held in honor of Charlotte Coursier, trust in other people is common and is a pervasive element of human life. We defer to the knowledge of others (testimonial dependence) and to their expertise (practical dependence): we rely on experts to tell us what the weather will be like, to fix our car, to give us a new haircut. Often, this deference is shallow and dispensable (we could in principle do it ourselves), but it can also be deep and ineluctable, as when we rely on electricians and other specialists.
This division of cognitive labor provides us with enormous gains, but does an increased reliance on testimony and expertise of others also come with costs? Fricker feels we do not reflect enough on this question, especially as the extent of both testimonial and practical dependence seems have increased dramatically in recent years. People increasingly rely on Google rather than internally stored semantic knowledge, and they increasingly outsource practical skills – navigation with maps, dead reckoning, and compasses is replaced by user-friendly technologies like GPS devices.
