I think this largely depends on who he goes to visit. It's very probable his status will prevent him from meeting people, but I think he can get around this. I'd love for him to meet my father. He's a recently retired immigrant chef, doesn't own a Facebook account, doesn't care who Zuckerberg is, but would provide him with great conversation on his struggles and challenges with technology as well as the best meal of his life. If I know someone good to talk to that is this close to me while being in the field of tech, I'm sure he can find good people to meet as well.

It will be as real as his visits anywhere else (not very).

I suspect that many/most people won't recognize him.
