This was already always the case. If anything, making this more accessible will reduce the barrier to entry for whether or not it's worth your time to take on a case. Instead of 50 lawyers spending 100s of hours on a case, you can have 1 or 2 lawyers + Astra working on it and if there's a case you can add more real lawyers.
1) Lawyers are not as naive as software engineers and will fight being replaces by new laws.
2) If they are replaced, OpenAI will take a cut commensurate with the amount in dispute (OAI, please credit me for the idea in the IPO brochure).
I am curious what level of trust established law firms treat LLMs with.
