Obviously lawyers should not be cheating with AI, especially when they don't even check it. But it does sound to me as if this is an opportunity to re-factor the process. We're carrying forward some ideas originally implemented in Latin, and which can be dramatically simplified.
I'm not a lawyer; I know this only in passing. And I am aware that there are big differences between law and code. But every time I encounter the law, and hear about cases like this, what I see are vast oceans of text that can surely be made more rigorous. AI is not the problem; it's pointing out the opportunity.
