I was thinking of discussion platforms but for general government I had a great idea: we know how to write and publish new laws but we are terrible at unpublishing outdated garbage laws. AI would be great for finding all laws that it thinks are dubious, impractical or otherwise undesirable in today's context and zeitgeist. There can be various manual deletion processes for different categories of absurdity.
It will be hard to design a formula that can only be gamed by making quality contributions.
A quality discussion requires parties who disagree, exchange of ideas and facts and ideally some kind of eventual agreement.
The hardest part is to make it enjoyable to use.
