>Yes it is. Mobile phones are incredibly not user friendly. They are just the best thing we have for the moment.
Who said user friendliness is some inevitability?
Some tasks (if not all) have some inherent complexity.
Even if we had strong AI, we'd just delegate the tasks to it to handle -- we wouldn't reduce the complexity of handling them ourselves, we have just bypassed it.
For consumers (not necessarily business use cases) you shouldn't have to pull your phone out every time you need direction, make a phone call, check your email, listen to a song etc...
