One of the greatest labor-saving inventions of today is tomorrow.

The quip treats procrastination as a “labor-saving invention”: by postponing work until tomorrow, one avoids effort today. Foss’s irony hinges on the language of modern efficiency—“labor-saving inventions”—to expose a very old human habit: deferring unpleasant tasks under the guise of practicality. The line also hints at the hidden costs of delay: what feels like saved labor is often merely displaced, compounded, or made more stressful later. As an aphorism, it works both as humor and as a mild moral warning, capturing how easily rationalizations can masquerade as productivity.
