I think it is. Before computers you would have had to write all that down on paper logs. By using code, you saved yourself time. If it wasn't less labor, you wouldn't have done it that way.
Computer used to mean "human who does math". Before machine computers, we had human computers. Machine computers replaced all of these human computers.
And without software, what then, make a bunch of books and mail it to all these people? On this site of all sites, it's blowing my mind that this kind of thing isn't obvious to everyone. I guess maybe it isn't if you were born before the internet, but man, I'm really surprised by some of these comments.
