For traffic court, perhaps, but these AI tools don’t seem guaranteed to not make this problem worse at broader scales.
These AIs will also be available to large firms, who are equally incentivized to use AI for augmenting argumentation through existing lawyers, but will also be incentivized to train their own walled garden powerful models in a way that poorer clients still would likely not have access to, and which individuals and smaller firms will not have the resources to train themselves.
These kinds of AI models could very easily serve to entrench and raise the cost of a defense by making it so you not only need a lawyer, you need a lawyer-backed-by-a-firm-with-a-LLM to be competitive at trial - making all existing problems even worse.
