science fiction idea, time travelers exist and fixed all the bad things in history.

resulting in a world who’s history is without any “bad incident”, no wars have ever happened, no violent crime can happen, it, even minor accidents can be undone, no one dies ever from accidents. if something bad happens you report it and goes in a backlog to be fixed by future time travelers.

(assuming no paradoxes)

you go to the dermatologist and finds a melanoma, too late now, so he just schedules an appointment for you 3 months in the past to have it removed.

will the society be just? bad ? good? is that a utopia? dystopia?

if no one ever experiences massive tragedies, will there be social change? or entrenched structures become permanent and unopposed? who about the psychology? getting a stubbed toe would likely be the worst pains someone ever experiences.

interesting concept.
