I find Project Cybersyn fascinating as a piece of history of how one country tried to use advanced technology to solve the problem of socialist central planning.
Are there any good histories (or thought experiments) of the advanced use of technology for more anarchist, less hierarchical (non-market, non-state) organisation?
The Zeitgeist Movement captured a lot of interest and The Venus Project was adopted as a high tech future economic vision. Probably rather technocratic. Not sure if work on this, or inspired by this came to much?
Parecon had some computer related stuff. Possibly just modelling, but may have been more?
Then I guess stuff like participatory budgeting. Liquid Feedback. Loomio.
Actually The Enspiral Network is an interesting example of economic organising using advanced tech.
