What costs less, laying and operating cable underwater or over mountains? That is, what are the relative costs of land and submarine cables for long distances?
Looking at the runs that follow the coasts of South America, SE Asia, and northern Canada, I wonder why some of them weren't run over land. (Obviously very many cables do run over land; this map only shows submarine cables.)
In my imagination, it seems easier to drop a cable from big spool on a ship than to run it over mountains, for example, but I really have no idea.
