“6. The Critical Engineer expands ‘machine’ to describe interrelationships
encompassing devices, bodies, agents, forces and networks.”

The most interesting line for me was line six; it is more interesting to understand machines based on how they work, how their mechanism are connected to each other, how they can connect to each other and how this can be used or exploited. For example, you see this many times in gaming where a fan would simply buy a game and use it whereas other fans would immediately open the game to hack it and release a hacked version onto the internet, often times much more interesting than the original.  In this case, this fan saw the game as something to be explored and changed rather than simply taking it for what it was.
