AI usage has been noticed by judges in court and they aren't fond of it.

AI is just a really good bullshitter. Sometimes you want a bullshitter, and sometimes you need to be a bullshitter. But when your wealth are at risk due to lawsuits or you're risking going to prison, you want something rock solid to back your case and just endless mounds of bullshit around you is not what you want. Bullshit is something you only pull out when you're definitely guilty and need to fight against all the facts, and even better than bullshit in those cases is finding cases similar to yours or obscure laws that can serve as a loophole. And AI, instead of pulling out real cases, will bullshit against you with fake cases.

For things like code, where a large bulk of some areas are based on general feels and vibes, yeah, it's fine. It's good for general front end development. But I wouldn't trust it for anything requiring accuracy, like scientific applications or OS level code.
