First of all, where are the applications in Google search? You just type in what you want, and the system uses AI to provide you with an answer. The fact that you can do that without having to think about millions of arbitrary applications is largely why it is so great. The fact is that people don't have an intuitive understanding of applications like "iTunes" they just have ideas of tasks like "listen to music." So I think the very idea of applications is flawed to begin with, and all applications will be made obsolete by a smart AI services, namely Google search.
Then there is the issue of over pricing these applications, when they could be free, which means that lots of people that are poor cannot acquire them.
But that isn't enough, behind the scenes, Apple has been screwing over developers with shackling licenses that I linked to above, and I don't care if they have been "incredibly smart" about how they have been screwing us over, they have still been doing it.
