"most of the world" is doing a seriously large amount of heavy lifting in this sentence. There are many regions that are served by a single line, more than you think. Even "well connected" places have fewer cables than you expect, and the frustrating thing is that you don't know that you can route around an issue until you try. BGP is really resilient, which is great, but if your path is not clear then you'll only realise it when the failover doesn't happen, you'll think there's a redundant path.
