look up any word, like timebomb:
Skills made vestigial by technology. Examples: reading maps (GPS navigation), making change (calculators & point of sale tablets), memorizing phone numbers, balancing checkbooks (or even sending paper checks), learning how to do something ("I'll just Google it").

Some sense that a person would be lost and ineffective without technology crutch. See vestdigital.
I threw out my vestigital road maps.
