God forbid we should actually interact with our fellow humans.

I guess the next step down this path is to replace waiters etc with robots - again reducing the amount you have to interact with other humans.

When I get in a taxi, I actually enjoy talking to the driver, asking about the local area, the news, and making both our days a tiny bit more interesting.

As the world population increases, and cities grow and grow I can only see this getting worse - millions of humans bunched together, and all of them scared to talk to each other.

(In case you hadn't guessed I'm not a city person)
