Because you could learn CAD faster??? That's the dumbest thing I have ever read. FIrst, learning CAD as an application, and knowing what you are drawing and how to draw it can take years. Second, Architecture has about as much to do with CAD as IT has with programming an alarm clock. CAD is a tool that Architects 'can' use to create their final drawings - after planning, research, design development, budgeting, customer meetings, contractor meetings, engineer and consultant meetings, code review... Then there's project specification manuals, contracts, testing and licensing, continuing education, etc.

I always get a kick out of people thinking that knowing how to use CAD is "Architecture". That's called being a CAD operator, or draftsman.
