According to All Things D, Siri co-founder Dag Kittlaus has left Apple just weeks after the company announced the iPhone 4S, which includes Siri technology built into iOS. The report mentions that Kittlaus wants to spend more time with his family in Chicago, would like "to take time off," and "[brainstorm] new entrepreneurial ideas." The resignation has apparently been planned for quite some time.
Apple has not commented on this matter yet.
