I worked on a project exploring this idea and an issue is that while each step in a user journey (get restaurants near me, show me menus, make an order, show me on a map) could invoke a distinct service, provided by different providers that just do that thing well, they all want ownership of the experience and the precious user data and prefer to consume input and render output rather provide output data for others to use - there’s no stdout to pipe. The upshot is apps do everything, which is the opposite of the Unix philosophy.
