I have to completely dis-agree with Woz here. The scenarios he is bringing up are things that a typical user of an Apple product would never ask. 95% of the people just want to look up contacts, addresses, movie times, sports info, schedules. Everyday things. Apple is optimizing for that. They day when most people are asking prime numbers greater then 87, I am sure Siri will be optimized for that.
And remember, Siri in its previous versions would send all recorded text to a server for processing, and a result would shoot back. In current implementation, Siri is doing all voice process on the device and handling queries directly in realtime -- optimization have to be made and limits do have to be imposed.
There is a difference between making an application to show technical prowess, and an application that is actually going to be used by consumers to solve everyday problems. And they are very different kinds of products.

Apple understands this.
