Man and machine.... I listened to an interview of a scientist who just finished submitting his research. He was able to show when we use a tool, a machine,...long enough, our brain creates new circuits for that particularal tool and make it as if it was an extension of our body like an arm! Let it go, it is nothing more than nuts and bolts and rubber. Its your creation. You are not losing that ability and can never sell it. Just dont lose it.
