Most certainly not. These were enterprise licensing agreements where the other party was a large corporation who had a lot of lawyers and time. I was using the human lawyer for these before switching to Claude legal. Both produced roughly the same output (redlines to fix the things that were disadvantageous to us).
Yes, that sounds like the former case. The fact that you were so satisfied with the switch supports the point. It's boring work that is routine and expensive. It's right to automate the first turn.
