I don’t dream much but I would like to live in a world where all the information published is free to modify and share (i.e. all the research data, hardware assembly instructions, firmware, microcode, software, books is copyleft). Intellectual property exists only as share-alike materials, you must publish the internals alongside with the end-user product (e.g. you can buy a CD, or download a content online). All the software is open-source, copyleft. Paywalls can only exist to cover infrastructure costs, you can still copy the content that is behind the paywall as long as you include the original author. This would break all the walled gardens of information.
