If a lawyer takes notes and puts them in a computer, or a cloud drive, or send it over email, they are still covered by attorney-client privilege, right? If they use an AI to do it, it's treated more like a third party no longer covered by the same privilege. If there's no court decision on this it only takes a bit of bad assumption to screw up with using AI.
To be fair, the attorney-client privilege should be completely technology/medium agnostic. If the intention is to have that info stay between client and attorney, nothing should change this.
