I'll just add that this has certain other interesting legal implications, because records in relation to a therapy session are a "protected confidence" (or whatever your local jurisdiction calls it). What that means is in most circumstances not even a subpoena can touch it, and even then special permissions are usually needed. So one of the open questions on my mind for a while now was if and when a conversation with an AI counts as a "protected confidence" or if that argument could successfully be used to fend off a subpoena.

At least in Illinois we now have an answer, and other jurisdictions look to what has been established elsewhere when deciding their own laws, so the implications are far reaching.
