> A serious question though, what does happen when AIs are filing lawsuits autonomously on behalf of the powerful

It won't just be at the behalf of the powerful.

If lawyers are able to file 10x as many lawsuits per hour, the cost of filing a lawsuit is going to go down dramatically, and that's assuming a maximally-unfriendly regulatory environment where you still officially need a human lawyer in the loop.

This will enable people to e.g. use letters signed by an attorney at law, or even small claims court, as their customer support hotline, because that actually produces results in today.

Nobody is prepared for that. Not the companies, not the powerful, not the courts, nobody.
