Another issue I see concerns the European Digital Markets Act. After all, it’s inevitable that competitors (perhaps including Meta) will want their devices to have equal access to the information collected by Audio Intelligence. Judging by the decisions Apple has made, it is likely that it will want to deny such access; which is why these new features will not initially be available in the EU.
There is also no doubt that hackers will try to break into the system, although this will not be easy at all due to the fact that the company has deliberately built in a security system. I suspect, but don’t know, that efforts will focus on the points at which data is exchanged between devices, rather than when information resides in secure enclaves on those devices. It also makes sense for everyone who uses iCloud services for their data to implement 2FA and choose strong passwords.
What about iCloud storage?
Another issue will be encryption, in particular the ongoing attempts to break iCloud data encryption by some countries, led by the UK. Even so, if it were possible to access the Audio Intelligence text stored in iCloud, only the summary data, not the recording, would be retrieved. The system is designed in such a way that no entries are ever made.
