The reason this approach lost to dynamic rendering is the absence of any sort of logic that would rebuild _only_ updated pages. The job of many, many web sites is to make it easy for people to add content to them. When adding something takes many minutes, the web site is doing its job poorly. Things are around today that are fast and that even offer the logic I refer to above, but the ship has sailed. We largely live in a world of cached pages that are changed via a complicated database-driven CMS.
