They’ll Die Out Eventually
When you look at today’s Macs, it appears this has already happened. Not only is there still no keyboard tutorial, the mouse tutorial is gone as well. Heck, you don’t even get a nice little character in an Apple sweater grabbing the menu bar with his hand and pulling out a menu, or zooming and closing a window. It is assumed that everyone today knows what a window and a menu are, and how to use them.
