Apple's success with Siri AI will be largely dependent on third-party developers. However, these developers have a lot at stake, as while their apps may become more useful on Apple devices through working with Siri AI, enabling the assistant could risk sidelining their own assistants. Several staple apps are still not working with an early version of Siri AI available to app developers, and it is unclear whether they will. If Siri AI rolls out this year with only support from some apps and not others, it could create a confusing experience for users and turn them off from using the assistant.
