but just imagine the brave new world, where a law firm has super-duper-frontier model and you're trying to argue with it in a court with your latest best local oss model (only 6 month behind the bestests ones).

Interestingly, I have a conflict with my municipality. I fed the articles of law and their arguments of why and how they apply to notebooklm and asked it for fallacies. It not only gave me the fallacies in their reasoning, but also an excellent counter argument and motivation why they are interpreting this law incorrectly. The result is now that they are handing over the entire case to an independent third party to evaluate which interpretation is valid.

This isn't any different than paying more for a better lawyer with a lighter caseload instead of using a public defender

So, best make sure the court has a significant internet outage on the day your case is scheduled, while you have your model running in your pocket? :)
