All machines are for laziness.
I think you are confusing machines with motors. Many machines do things that simply are not possible without. A bicycle, for example, is not at any less work than walking, but it enables you to go faster than you can run. Menually operated sewing machines produce stitches that would be infeasible by hand.
Motorising any of those machines could be considered lazy, though.
This is totally wrong.
Some machines are capability amplifiers.
Other machines are shit puking buck passing time sinks.
