This starts to touch on one of the reason every "personal assistant" is crap: they're basically just a verbal command line. Their only real value proposition is basic interactions when the user's hands and/or eyes are busy with something else. Until they can get smart or fluent enough that they can rival the effectiveness and accuracy of hands-on-screen interaction, the use cases will remain fairly niche. More programmable, multi-modal interaction is a step in the right direction, but it'll require a lot more.
