Object-Oriented Machinist

I was exploring some computer programming software information and I discovered this analogy. Is so good, I have to share:

…Simply stated, object-oriented design is a technique that focuses design on the data (=objects) and on the interfaces to it. To make an analogy with carpentry, an “object-oriented” carpenter would be mostly concerned with the chair he was building, and secondarily with the tools used to make it; a “non-object-oriented” carpenter would think primarily of his tools. Object-oriented design is also the mechanism for defining how modules “plug and play.”

I know what I am. What kind of hobby machinist are you?
