I ' m not totally sure since most of the artists I listen to write their own , but I can give my thoughts . I suppose some people simply have talents in different areas . Some folks are better at writingcomposing , others in p erformingrecordingplaying I guess . There are definitely artists who write their own everything but it ' s very understandable why some artists don ' t . Not even necessarily because they can ' t , I suppose some of them just prefer not to . <| sep |> I would like one please . I filled out the form . <| sep |> Yeah , that ' s why we don ' t teach addition in math anymore . Shit ' s moved on . I ' m not sure what field you think Edison is relevant to , but in EE , we go back before Edison to Ohm and Faraday because to understand the field you need to learn the underpinnings . Even if you don ' t write compilers , you use state machines , and if you don ' t understand them , you probably use them badly . Ditto Boolean algebra . Why are we doing this ? I think that some of the biggest mistakes people make even at the highest architectural levels come from having a weak or broken understanding of a few simple things at the very lowest levels . You ' ve built a marvelous palace but the foundation is a mess . Instead of a nice cement slab , you ' ve got rubble down there . So the palace looks nice but occasionally the bathtub slides across the bathroom floor and you have no idea what ' s going on .
