The issue is that communications with A.I. are not privileged like client-attorney. There was some judge that made that ruling.

Feels like a conflict of interests to me, I'd guess friends, neighbors, children and nieces of that judge enjoying their livelihood by charging for legal services. While legal services are now available under substantially lower rates and with a lot fewer conflicts of interests from A.I. providers...

This is a completely straightforward application of existing law on privilege. To maintain privilege, among other things, communications must be confidential.

Chatting with Claude breaks confidentiality: chats with Claude are subject to arbitrary inspection by Anthropic employees, not to mention the issue of model training.

You can use self-hosted LLMs without breaking privilege. And funny enough, law firms like Latham & Watkins are now buying Nvidia GPU clusters for this purpose.

They ruled that it's like a journal, or a tool like a search engine. This seems fair.
