Rules:

  • The messages can go as far back as the beginning of the 7 day period (the moment you found out about your assassin is after you)
  • You can only send the messages if you have cell signal (maybe don’t hide in the woods, you assassin might be there, and you don’t get a do-over 🙃)
  • Your phone is immune to damage and malware (although spyware and keyloggers can still be on there, but they can’t affect the system, just on “read only” mode). Auto-updates are now disabled by default
  • If assassin got your phone, they could send false messages to trick your past self. (Don’t lose your phone!)
  • At the end of 7 days, the Assassin will just drop dead due to time travel limitations, time travelers cannot survive longer than 7 days in the past (yes, the assassin is a time traveler 😉)

    “Oh, a text from future me? Let’s see what it says…”

    “FM: Ninja assassins are after you. You know what you must do.”

    shuts off phone nods solemnly “Set myself on fire.”

    I don’t. I’ll share this technology, preferably with trustworthy competent people. At last, I’ll probably figure out how that decision lead to my assassination.

    I wouldn’t warn myself because I don’t want to get caught in a groundhog day, butter fly effect scenario.

      I mean, you could just give your self a limit.

      Add a “Iteration 1” to the first message, and the 2nd iteration of you should append the message with “Iteration 2” and so on…

      If you still get warned of death in Iteration 500, then maybe then you can give up.

      At least try to survive for a few timelines.

        I would’ve created 500 alternative timelines by then, and in all of them my peers would have to live through my death. It sounds selfish to put that burden on them for the chance of creating one timeline where we maybe live happy, instead of just accepting my fate and leave only one family behind.

        I might tell myself that it’s really important to live the next seven days if they were my last.

        Playing with time doesnt sound wise to me.

    Step one: I clone my phone allowing two phones to contact my past self.

    Step two: “Lose” one phone, after turning on find my friend on the lost phone.

    Step three: Send past self false information while keeping constant tab on the assassin who believes they have an edge.

    Step four: Hit the assassin before they hit me.

    Assuming you can change the future, you can send a message with your location history every x minutes to your 1-day (or more) ago self. You will have to encode it (and I guess this should be done outside the phone) in a way that the assassin can’t spoof a message. You’ll have to figure out that encoding as soon as you find out about the assassin since that’s your message travel limit anyway. When you start receiving messages you follow that location history and then stop following it when you stop receiving them because something went wrong there. Eventually some instance of you might make it 7 days.

    What time travel rules? See: https://tvtropes.org/pmwiki/pmwiki.php/Main/TemporalMutability

    Going with “overwriting the timeline,”

    • buy yourself an hour to live on the first day, should be easy enough

    • make fat cash with options trading in minutes

    • buy hella security

    • repeat until the seven days have passed

    I would also rig a “dead man’s switch” on my phone in case the assassin ever does get me, to reset things (by telling my past self of my current situation, so they can avoid it).

    I’m leaving my phone somewhere very far away from my actual location. Check and mate, assassin.

    First of all, if it’s my number sending messages back in time to myself, I could easily convince myself it’s me by sending a list of my passwords back in time.

    Second, tell myself that I’m screwed no matter what because there’s no way I could defeat a professional assassin (assuming it’s professional), especially one from the future, and to probably just hang myself or some other form of suicide in order to mock the assassin by not letting them get the kill.

      Turns out you were the assassin all along and sending yourself messages to prompt pre-emptive suicide was your method.

    Every hour send a message back to the start of the 7 day period + 1 second for each elapsed hour “still alive at <current time>” At the first one hour mark send a message to three minutes after the start of the period. 168 hours in a week, texts with survival status will be done a bit before the three minute mark of constant messages. This message describes the situation. Now I have insight into when the assassin will get me, to an hour. Don’t change my behavior until the hour span leading up to the last still alive message, go nuts traveling randomly during that time until the number of still alive text messages changes After surviving for a week send a final message back in time to the very start “your phone is trying to kill you”
