There was once serious talk about ChatGPT becoming deeply woven into Windows ecosystem. The momentum seemed unstoppable at first, then quietly faded into the background.

Similarly, the vision of ChatGPT becoming core to Apple's software fabric generated massive hype. Yet that ambitious integration plan also stalled.

When two tech giants independently pursue the same AI integration strategy and both efforts fail to gain meaningful traction, it raises an interesting question: what's the underlying reason? Is it the technology, market readiness, user demand, or something else entirely? The pattern suggests there might be structural challenges to mainstream AI integration that go beyond individual corporate execution.
