Recently came across an AI tool called Nuwa, and its features are quite interesting—just take a casual portrait, and the system can directly compile the person's publicly available online information through facial recognition.

At first glance, for those who frequently attend industry summits and various offline events, it’s indeed convenient. Quickly understanding the background of attendees and saving social costs.

But upon closer reflection, it feels a bit uncomfortable. Essentially, isn’t this just an automated aggregation of publicly available information? On the surface, it’s called an "AI recognition tool," but fundamentally, what’s the difference from human flesh search or social engineering databases? A single photo can reveal all your online traces—how much privacy space is left?

Where are the boundaries for tools like this, and who should regulate them? It might be more complicated than it appears on the surface.
