Australia: carrying out elections.
Voting is compulsory and you will be fined if you don’t vote without an acceptable reason.
But because voting is compulsory, it’s extremely easy and accessible. Waiting in line for more than 15 minutes is a long wait. Even in the suburbs you’re not usually more than a five minute drive from a polling place.
If you think you’ll have trouble getting to a polling place on election day (a Saturday), you can request a postal ballot or vote early at a different polling place.
We have an independent electoral commission federally and in each state/territory to organise elections (depending on which level of government you’re voting for). They also handle district boundaries to remove gerrymandering.
All ballots are marked and counted by hand. The counting process is open and transparent: any candidate can send people to inspect the counting process and ensure there are no irregularities.
A malicious gene drive. Basically, use molecular tools to ensure that a gene is always passed down from a parent to its progeny, regardless of the other parent’s genetic makeup.
Many choices available: propagate resistance to a pesticide for mosquitos, guarantee Huntington’s disease in a family, or crash a population of beneficial special by reducing fertility, to name a few.
