It occurs to me looking at the map that a tourist in modern day Paris would still be well-served by this network.
That thought also made me wonder how central Paris' modern metro system overlays onto this. Here's a quick little visualization: https://stirring-biscotti-a978fa.netlify.app/
If you're traveling to or interested in Paris and its history, I really enjoyed "Parisians: An Adventure History of Paris" by Graham Robb. Has some good, accessible and entertaining history relating to (among other things) the construction of the metro.
That's not a surprise. People orient their lives around what they can do. Thus, things like this become self-fulfilling prophecies. You build it, they come, they add the demand, so you keep it running. It certainly does and has happened that cities have changed majorly at various times because of changes in transit, but it's not particularly common. In most cities even where transit has been torn out, you can see where the lines used to run because that's still a high demand corridor today.
