I now think that apps as an idea could disappear at some point. Users will simply tell Siri or another tool what they want their smartphone or computer to do, and then it will be developed ad hoc.

There may be some backend services, such as Yahoo Pipes, that you can or should use, but the concept of an app that you download from the store will probably disappear.

But that depends on whether these AIs can crack the tough nuts. At the moment, they tend to build things they have seen. But first, you can combine all kinds of things from parts, and second, the AI can then hire people to make the missing puzzle pieces.
