I don't know really, I'm just trying to come up with the least bad solution. There's a lot of corruption even in the scientific community, and major disagreements even on supposedly "settled" science.
Maybe some kind of international organization with (elected) representatives who manage rule sets and audit AIs with the help of scientists. Maybe an open source authority of some kind.
Why should scientists/platform creators be authority?
Not that I necessarily disagree, but questions like these should have answers with a lot of rational arguments behind them.
