I'd argue that a lot of modern web engineering pretends to be built for problems must people won't have. So much resume-driven-development is being done on making select, easy parts super scalable while ignoring some elephants in the room such as the datastore. A good example is the obsession with "fast" web frameworks on your application servers, completely ignoring the fact that your database will be the first to give up even in most "heavy" web frameworks' default configurations without any optimization efforts.
