I have ideas for crazy things.  Here are some:<p>Make a Wikipedia for code.  Not a wikipedia <i>about</i> code, but a Wikipedia where the pages <i>are</i> the code.  No references to outside tools&#x2F;libraries, all the functions are either in the base language or references to other wikipedia-of-code pages.  The pages are presented in a literate programming style.<p>Bring back the Inferno OS, but replace the original VM (Dis) with the Microsoft CLR.<p>Make a P2P publishing system for scientific publications.  Let the contributing scientists have individual accounts, and manage reputations with a blockchain reputation system.  Let people also donate their CPU cycles to scientific computations through this system.  Require publications to store their data in a database format that your system&#x27;s client can query and process with some programming language.  Require all data tables, and results that appear in the publication&#x27;s text be expressed as functions performed on data queried from the database (or potentially databases from other publications.)
