Every technology is a metaphor. That much is clear. The difficult matter is to sort out whether this is a primary or secondary function.
Which is to say, did we initially make this universe of instruments, machines, tools, and devices as a way of talking about our condition, only then to discover, post hoc, that all the amassed hardware also proved useful for solving various practical problems (washing dishes, killing neighbors, etc.)? Or did it work the other way around?
Did we set out to kill our neighbors, say, and then notice that the sword was a lovely way to say “violence”?
