what does this mean?

It's a mix of metaphor and imagery.Not a good text for a learner to study.

He has already asked this question.

could you give me a further explanation about these two sentences as :where you can interact with real people on the telephone,where ,if you call you broker or your bank, you don't end up somewhere in Ohio.
what the two "where" mean?

"A world where" means "a world in which".

The writer is describing an ideal, imaginary situation, an ideal world in which for instance, when you make a phone call to your local bank for assistance or information, the call is not automatically transferred to a call-centre somewhere else.

thank you so much. I have been thinking so long and you have helped me out.
how about this one following that"where self-confessed killers are not set free because somnebody forgot to read them their rights.

Part of the US legal system is a requirement that those arrested are read a list of rights so that they understand they can get a lawyer, etc. If the police do not read a suspect his rights, the suspect will be released by the courts. The author is making up a situation where someone who is obviously guilty "self-confessed killer" is released on a technicality.
