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.
But you could still arrive if you walk instead of using the bicycle. And I am sure you can do the same stitches by hand, it just takes forever.
Same with coding agents. I could do it by hand. It just would take much longer. Often so long that it would be impractical.

What? Have you, uh, ridden a bicycle before...?

Of course it is, at equivalent distance.
