Could artificial intelligence that is capable of complex decision-making pose a threat to humanity?

I think advanced AI could become a serious concern if we're not careful. The main issue is that once AI systems start making complex decisions independently, we might lose control over their reasoning process. For example, as a UI designer in Shanghai, I use AI tools daily for layout suggestions, but I've noticed they sometimes propose designs that look polished but completely ignore user accessibility needs. That's a small-scale example, but it shows how AI can prioritize efficiency over human values. That being said, the real danger isn't the technology itself, but how we implement safeguards - right now, the development seems to be moving faster than our ability to set proper boundaries.
