In the future we will see many different way to communicate with other people. We will use not only airplane or internet to communicate but also transatlantic tunnels, highways from Europe to Asia to North America. The Trans Global Highway, which was proposed by Frank Didik, would physically link by highways and by rail transport, all continents and major population centers, with the present exception of Australia, which, in the future, may be linked via very long suspended, pre-formed, suspended underwater tunnels from extending from the Philippine island chain. The Trans-Global Highway would include road transport, railroads. oil and gas pipelines, electric and communication cables, fresh water pipelines could minimize the concern of flooding as presented in the theory of global warming. Of course this kind of construction will be a Kardashev 1 type of civilisation.
Some of these projects were covered in the Extreme Engineering TV series by Discovery Channel.
