Ternus Pushes Apple to Accelerate AI as Siri Upgrades and Executive Changes Loom

The push signals changes to Apple’s engineering cadence with a plan to evolve Siri toward a proactive, agent‑style assistant.

Overview

  • Citing Sunday’s Power On newsletter, Bloomberg reported that CEO John Ternus privately urged software chief Craig Federighi to speed Apple’s AI roadmap beyond incremental Siri improvements.
  • Multiple outlets say Apple plans expanded Siri control of its own apps to reach public users in December 2026 and a preview of third‑party app support in spring 2027.
  • Mike Rockwell, vice president leading Siri engineering, is reportedly considering stepping down from his role or leaving Apple in 2027 and his responsibilities would likely be split between Amar Subramanya and Sebastien Marineau.
  • Apple is experimenting with a new development cadence that gives engineers six weeks for coding and exploration followed by two weeks for integration to shorten delivery times for AI features.
  • Apple’s technical path favors App Intents over pixel‑based ‘computer use’ automation because it is faster and more private, but it depends on broad developer adoption that remains a bottleneck for fully autonomous Siri agents.
