If you possessed such a device then errors in your "predictions" would be indicative of another party using a similar device. As such, I assume multiple parties would soon discover each other, engage in an incomprehensibly complex time-battle, and there would suddenly (instantaneously in all patched timelines) be only one such party.

Furthermore, I imagine it would be very easy for such a party to accidently blunder into a situation where they lose control of the time-messaging device, erasing all evidence of its own existence and leaving the timeline perturbation-free until such "time" as reverse time travel is rediscovered.

In the book Singularity Sky [0], mankind invented the first time-looped computer, and it cycled up to a godlike overlord. After making a lot of very disruptive changes (which of course seem to be immediate to everyone else) it seems to have become surprisingly disinterested or uninvolved.

Anyway, it has only one hard "commandment": Nobody can violate causality anywhere inside its own historic light-cone, since doing so could be a potential attack (or competition) to its own existence.

Book was so much better than accelerando

Future Diary has some pretty cool time battles. While it's not as good as death note, it definitely has it's moments. https://m.imdb.com/title/tt2069441/?ref_=m_nv_sr_1

As a fan of time travel movies, I'd watch this.

You may like the anime Steins;Gate then. The plot is based on the idea of sending a small amount of information back in time and changing the sender's present, and then finds that another organization has been using this and is trying to control the world with the power.

Everyone in this thread should try Primer! Great little movie about a similar concept (smaller in scale though). Tries really hard to stick to its own rules.

Or an episodic series where every episode has a new main character inventing time travel and then accidentally destroying the conditions that allowed then to invent time travel.

Sounds like Dark.

It's approximately the plot of Primer
