I think AI politicians or complex algorithms just risk being a more complicated form of legalese that even less people can understand (legalese in code/math form). With law in code form like that, you need to demand much more of the education system (scary!) to allow people to vote on PRs, if you even do that democratically. Otherwise, even more faith is put in the hands of the designers/core-maintainers as representatives, much like we already have. More ways to obfuscate direct effects and hide side-effects.

I truly think there is something there though, something from the open-source process that can make government more efficient and productive, but it's probably not in the way we are thinking. It probably looks less like software maintenance and more like science, dare I say political science. Crowd-source solutions and organize experiments across counties and states in a way that's data driven, not politics and need-for-reelection driven.

No AI necessary.

Just make a pull request with the law you want to implement or amend

another way to 'use' github I guess :D or plain git?
