Movie Matrix and establishing credibility

The topic of "on the Internet, no one knows you're a dog." reminded me of the sci-fi movie Matrix, and Jean Baudrillard.

Jean Baudrillard, a French philosopher, claimed that the world we live in has replaced realities with symbols. He used the terms simulacra and simulation to explain these phenomena, and he even claimed that we now cannot distinguish between reality and simulation. The main idea of the sci-fi movie Matrix has roots in these philosophical ideas. The movie Matrix depicts a world where there are no clear borderlines between realities and the world of simulacre. Of course, our world is different from what the Matrix describes. But, we can still find meaningful implications for this topic: how we can establish credibility on the Internet?
