    Life will find a way. Going back can be used to create nuclear winter but even then, life will go on.

    To completely screw over the world, I would go into the future and acquire the source code for a general AI.

    Then the world can be locked down and robots can be built to abuse every human and sentinent being individually, for a very long time.

    Well current events lead me to believe that allowing the orange turd to live would do the job nicely so in the spirit of laziness I’d do absolutely nothing.

    Land the time machine on top of the first animal to walk on land. Don’t even have to get out of the machine.

    Go back from 2026 to 2024. Report a pet has gone missing and you heard that an immigrant neighbor ate it. Come back to 2026. Book your dream vacation at the Trump Gaza resort.

    Go back in time and do something to prevent Vasily Aleksandrovich Arkhipov from becoming the Executive Officer on the B-59 Soviet nuclear sub in October 1962. He’s the guy who talked the Captain and the Political Officer out of launching the nukes when they thought they were being attacked by the US Navy during the Cuban Missile Crisis. His persuasiveness is generally considered to have avoided WWIII from starting then.

    Shoot Arch Duke Ferdinand. Few people even now about it today, but he was subject to a horribly mangled assassination attempt that many scholars belive would have set off a major war in Europe had he died.

    You’re going to pretend we’re not on that timeline right now? I see your play, time traveller.

    Wait until I’m about to die, then go back to when the first land-dwelling animals first started coming ashore. I’d bring a bunch of cockroaches with me and then I’d die there. Either the roaches or my decaying corpse will hopefully cause enough change to the timeline that humanity never develops in the first place.

    I think that’s the most I could screw over the (human) world.

    Can I appear anywhere? Pop into white house or Kremlin during the Cuban missile crisis and say: I’m from the future, you must attack, or… Then travel back to the future without finishing the sentence.

    Go to back to the big bang. You presence alone will butterfly effect the earth out of existence.
