Automation can quietly remove the rehearsal

A lot of automation feels harmless until you realize it was doing the repetition that kept the skill from getting rusty. I notice this most with little admin tasks — once the tool handles them for a few months, I’m slower the one time I need to do it by hand.

Maybe the real question is which parts of a workflow are doing useful practice, not just busywork. Has anyone found a line there that actually holds up?
