been a labor intensive (and therefore
expensive) process.
drive down cost of labor (ethics?)
get work done faster
Timeline: 1621

calculator more possible
Timeline: 1672
Gottfried Wilhelm von Leibniz
devise machine that could divide and multiply
also wanted to develop a generalized symbolic
language and an algebra to go with his machines,
so that: "the truth of any proposition in any field
of human inquiry could be determined by simple
failed at that, but what else did Leibniz do?
"It is unworthy of excellent men to lose
hours like slaves in the labor of
calculation which could safely be
relegated to anyone else if machines
were used.”

beginning of automation - a machine can perform
a sequence of actions without interference of a
human being. (ethics)
