Mark Gurman reports that the new Siri is delayed again, from iOS 26.4 next month to 26.5 or later:

As recently as late 2025, internal versions of the new Siri were so sluggish that people involved in development believed the company would need to delay the introduction by months.

Apple is very set in their old processes and release cycles. But OpenAI ships major new features multiple times a month. I don’t see how Apple can be competitive in AI unless they rethink how they work and release software.
