What will AI systems be like in the near and long terms? Basically, we'll get the AI that people are willing to pay for. Consequently, many specialized applications will appear long before AI demonstrates its "Manifest Destiny" of human-level general intelligence. The AI demonstrations and applications we're going to see in the near future will trend strongly toward "cognitive prostheses"-systems that do well things that humans do poorly or don't like to do. Both near-term and far-future systems will need to interact smoothly with humans, which will put special constraints on them. In particular, to build systems that we'll trust and want to use, we'll need to carefully consider and craft their implicit and explicit values.
