In the latest edition of the Power On newsletter, Mark Gurman hinted that adoption of Siri AI could lead Apple to introduce fees for advanced features. Apple is still in the early stages of convincing customers that its AI technology is worth using, let alone worth paying for. The Siri and Image Playground features have significant server resources and high costs. Based on this, Gurman believes that more conversational, world knowledge and generative AI features will eventually get rate-limited and then require a fee.
