Apple delayed its upgraded Siri due to reliability issues, according to Apple executives Craig Federighi and Greg Joswiak. They explained to the Wall Street Journal that while initial results were promising, the improved Siri, aiming for context awareness and app action capabilities, didn't meet Apple's quality standards. The delay was deemed necessary to avoid disappointing customers with an unreliable product, prioritizing quality over a rushed release.
