Siri Recap is an electronic record of a conversation that includes timestamps. Imagine for example that during a scheduled meeting with my boss, he threatens to fire me for not doing something illegal. I now have strong evidence that this was said (even if it cant be officially attributed to him) during the time I was in a meeting with him. Not saying this will hold up in court, but it certainly is more damning that having written notes (not to mention the fact that my boss probably wouldn't say this when I am taking written notes).
Fwiw, imo, you should assume everything you say (and write) is recorded going forward.
I imagine no single spineless impotent modern court would risk a wrath of our new benevolent AI overlords calling them all criminals they really are.
Many powerful and interesting people were having powerful and presumably private conversations in rooms because they say people walk in and out and legally CH could not record without consent. But what they could do was “collect metadata”. Emotional and tonal analysis is metadata. So is time, date, location, username (each user had their own mic stream), email, etc. Transcription is also metadata.
Essentially the tech has left the laws in the dust as you could now reasonably and legally record enough metadata to accurately resynthesize a recording.
But of course, I am not a lawyer.
is a telephone call a recording?
What Apple is doing in Rewind is as legal as if you were to take a contemporary transcript of a conversation. That's not illegal.
It's legal even if you're a skilled shorthand transcriber and get every word. That's Rewind, if I've understood it correctly.
