<p>I was thinking that Japan and Switzerland likely have good rail networks because the buildable land is severely constrained by geography. In those cases mountains, and connected only by thin linear corridors (valleys and near coastlines).  Look at this map of Japan:  The green areas aren't just natural areas, they are too mountainous to build cities.<p><a href="https://www.eorc.jaxa.jp/ALOS/en/dataset/lulc_e.htm" rel="nofollow">https://www.eorc.jaxa.jp/ALOS/en/dataset/lulc_e.htm</a><p>In other places with large, flat expanses, human civilization spreads out to an extent that expensive railroads just can't serve the needs/desires of people.  You could artificiallly constrain it, but you know what? People in general just don't like being told what to do.</p>

<p>I just listened to a fantastic multi-hour Acquired (<a href="https://www.acquired.fm/" rel="nofollow">https://www.acquired.fm/</a>) podcast episode on Google and AI that talks about the history of Google and AI and all the ways they have been using it since 2012. It's really fascinating. You can forgive them for not focusing on Reader or any of their other properties when you realize they were pulling in hundreds of billions of dollars of value by making big bets in AI and incorporating it into their core business.</p>

<p>I'm going through this decision right now. I agree, you are building a product with an unproven market and lots of time to grow organically, maybe you do want to start small and scrappy. Build something you can easily throw away and start over with. Build something that gets you to market as quickly as possible so you can pivot.<p>OTOH, If you are trying to sell the idea to investors and large companies that you are a serious player and have a plan and know-how to grow and scale your service quickly, maybe you do want to show that you have the design chops and ability to actually scale your product. Take a look and ask yourself, "Does my business model only work if it scales up dramatically, far beyond the capacity of a single database?" If the answer is "yes", start with a scalable architecture to save the 100+ person-years and endless gnashing of teeth it will take to untangle your monolith (been there.)</p>
