It talked about a trend from either-or choices to multiple choices. As technology evolves and more specialized applications appear, there will be more choices about how to deal with them. The idea that we can accept one language to support a growing number of different number of applications is naive. Ada has it's place. Perhaps Ada 9x will expand Ada's role--it provides multiple choices through annexes. Why would you program an expert system in Ada? Of course the tool use do use could itself be written in Ada--CLIPS has been.
