This isn't just theoretical anymore – it's happening right now. Traditional law assumes humans make decisions, but AI systems learn and adapt on their own. They can make choices their programmers never anticipated. It's like having a student who becomes smarter than their teacher, then does something completely unexpected. Your Data, Their Algorithms We all know AI needs data to work – tons of it. But here's the kicker: most of that data is personal inf...
