The document discusses the past, present, and future of content management systems (CMS). In the past section, it asks questions about how websites were created 20 years ago, which tools and technologies were used, and if they persisted over time. The present section notes that the internet is now ubiquitous and accessed through mobile devices, and questions if current CMS need to evolve. The future section speculates on how information will be dealt with and accessed going forward, whether as documents or streams, how semantic it will become, and if information can expire or lose value over time.
