@Professor_Stevens @Infrogmation One of the things non-techs (such as myself!) have to have painfully explained to us is: machines need maintenance. They don't run forever by themselves. As you say, they run "for a while," but then when they stop working, we're like WTF? But that's just what happens. It's predictable. It ought to be written into budgets and regarded as an immutable operating cost. But like the OP says, that "doesn't make money," so shit breaks down. All. The. Time.
@Professor_Stevens @Infrogmation There's a directly parallel problem of "it doesn't get votes," too.
