I have a relative that works in the trades. You know, the kind of work that four year university graduates are going to after leaving their white collar world (apparently, occupations that require onsite execution cannot be outsourced and the dexterity required is beyond robots, at least so far).
Anyway, take away his smartphone and his work environment is what life was like before the 1980’s. No digital design or planning software. No credit card transactions. No email. In fact, since most of his contracts are just verbal handshake agreements, his business culture could be the 1780’s.
