I'm talking about the learning process... whereby a tool, first unfamiliar to the user, after some period of time, becomes transparent to the user. For example someone learning to play an instrument.
I assume when someone encounters their instrument for the first time... that's "present-at-hand". He's conscious of the instrument, and has to be conscious of almost every motion. After many years practice it becomes "ready-to-hand". Even operating complex machinery like an aeroplane can become ready-to-hand.
But what is the process by which this happens. Does Heidegger talk about this?
Also... what is the role of language here... language is clearly involved in the learning process... but when something becomes "ready-to-hand" has the brain bypassed language now... are we operating without language until we return to the "present-at-hand". Is language still operating or is it just an intermediate tool to get to mastery of a skill?
