"I think that lawyers who understand how to effectively and ethically use generative AI replace lawyers who don't,"
There are three kinds of people in the world:
1. Those who strive to behave ethically.
2. Those who don't give a damn about ethics at all and make no bones about it.
3. Those who pretend to behave ethically.
People who want to "do the right thing" aren't a problem. They sometimes make mistakes, but try to correct them. I think this is most people, like more than 80%.
People who don't give a damn aren't really a problem either, since in a world populated by mostly good people, they'll ultimately be shamed and marginalized or end up in jail.
People who can successfully project the illusion of behaving ethically when they have no intention in doing so are a HUGE problem. While there aren't a lot of them, they're highly concentrated in positions of power and hold most of the world's wealth.
Maybe in the field of law, you can sort of cancel out the pretenders over time, since everything is (ostensibly) reviewed, so maybe "AI" will help the unabashedly unethical lawyers to self-destruct, but everywhere else, the problem remains, and "AI" is mostly going to make them worse.
