MacWrite and MacPaint, a Coral Reef
Software evolves like a coral reef. I've written about this many times. Something happens, a ship sinks, some fish live in the wreck. Their predators come there too, because there's food to eat. Then they die and their skeletons form a new structure for life to cling to. Eventually you have a thriving ecosystem. No one uses MacWrite or MacPaint today, but in a sense we all do, all the time.
I have fond memories of using them on the Mac 128K at school. The yellowish plastic of the case made it look like an antique compared with the Apple IIc and IIGS, which were much faster and had cursor keys.
