Apple has delayed its AI features for Siri. According to one exec, part of the problem was the "decision to publicly promote the technology before it was ready."

Apple Inc.’s top executive overseeing its Siri virtual assistant told staff that delays to key features have been ugly and embarrassing, and a decision to publicly promote the technology before it was ready made matters worse.

I applaud that exec's honesty. What happened is more common than you might think.

The core issue? AI is inherently probabilistic. You can't force a model to work well. That means you can't safely say that an AI-based feature/product "will" work by a certain date; you have to build it first and then announce that it "works now."

This is a far cry from app dev, in which you have far more control over the product and can provide reasonable expectations of functionality far in advance.
