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.
> Before computers
Computer used to mean "human who does math". Before machine computers, we had human computers. Machine computers replaced all of these human computers.
People *did* write down these logs, manually, and submit them.
Before it was less labor, they might not have done it at all. Computers let you do things quicker. So you do more things.
