The act has to be small(ish). You can’t say “Make everyone vote a certain way!” As an example I’ll give mine.
- Take all of the money I currently have in savings and invest in Nikola Tesla and attempt to slander Edison.
- Ride the train with Edgar Allen Poe and make sure that he made it to wherever he was going safely and keep an eye on him for a few days to make sure he was ok.
- Sit on top of the library of Alexandria with a SOPMOD and several hundred magazines worth of ammo.
Update: gotta say, there’s a lot less “save my favorite musician from death” or some such than I thought there’d be.
That was less for you than for the people who come after, still ignorant of the crimes of Edison. A just world would not even remember Edison’s name.
We hardly live in a fair world, much less just.
Totally the wrong place in the thread, but I think just going to the Library, proving that you are from the future with some basic knowledge of chemistry, and telling them that they need a backup in the caves of the Sinai Desert would probably be my go-to. Give them some pointers on multi-millennium document storage.
