I've sometimes wondered what would happen if World War 3 mainly involved the destruction of the internet and/or the GPS system. Would it inevitably lead to a hot war? Would modern economies really collapse?<p>I have no doubt that I could navigate a world without the internet and GPS, because I did for half my life. And I suspect shipping goods to consumers would be hindered, but have we gotten to the point where shippers and receivers couldn't work it out by phone? Would the phone networks survive? I know the landline system is a shadow of its former self, but would it suffice?<p>It's popular to say that the internet has created a new economy, but the underlying realities haven't changed. People need food, shelter, clothing, transportation. I think we could deliver that without the internet, though it would be painful. All the doom-saying otherwise just seems hyperbolic to me, though.
