The present systems have more attributes than “they somehow work, but slow”. Think about separation of power and decentralization. Slowness is a feature here. If you want to radically change a society where decisions are carried out by any number of individual actors, you need to take them with you by either using military force, money or convincing them otherwise. In any case this is a project that could also fail. With an algorithm, you could change it today and it would be in action without many even noticing it.

I could get behind a simple and transparent tax system, where you just see in realtime what money you give while beeing sure that big company has to do the same, without gaming the system.

But I am not sure the system that decides on these rules should be another system.
