People often get carried away thinking about linear progression from the current state when the general problem is NP-hard.

With Siri, however, I'm not interested in it being a person, but something that can help set reminders, timers, appointments, and dictate text messages while I drive. That's huge for me. Rather than breadth, if Apple focuses on depth then the problem is more tractable because you have more context with which to reduce complexity.

Apple's R&D is applied, so it will have a product focus and get to market quicker. If they can make Siri really good at a specific number of tasks then people will understand what it is good for, rather than be disappointed, and it will improve faster.
