Borg Introduction

social class:

focus on the middle ground--not production or consumption but maintenance and repair done by people who do not create or own the item

it wasn't clear originally who would repair cars and what their professional and social role would be.  It was worked out by different groups competing for particular roles and trying to redefine roles once they had them

When the automobile begins to be criticized in the 1960s, mechanics get more negative publicity
computer built into cars for control and monitoring took away control from mechanics

auto repair knowledge is not easily codified, so it cannot be deskilled to people just following instructions
on the other hand it is not easily formalized to give professional status
it is still tacit (sense based) knowledge, craft knowledge rather than scientific

how does personal experience inform this book?
