Thats actually a really good dilemma if you think about it. Like if everyone doubles it you basically don’t kill anyone. But you’ll always risk that there’s some psycho who likes killing and then you will have killed more. And if these choices continue endlessly you will eventually find someone like this. So killing immediately should be the right thing to do.

    At some people you will run out of people to tie to the tracks.

    How many branches is that going to take? Just out of interest.

    math checks out. log2(8 billion) ~= 32.9

    It's a little more complicated than that. You have to be summing everyone who is still tied to all the previous tracks. It needs to be a geometric sum formula.

    Some day it reaches a person that thinks...

    Well, 4 billion people less is better than someone being able to wipe out humanity...

    (it would also solve many problems lol)

    (and that point would be after 32 people had the choice...)

    This is really the only answer. The only thing that makes it "hard" is having to face the brutality of moral calculus

    Now, what if you’re not the first person on the chain? What if you’re the second one. Or the n one? What now? Would you kill two or n knowing that the person before you spared them?

    The thing to do is kill now even if it's thousands. Because it's only going to get worse.

    The best time to kill was the first trolly. The second best time to kill is now.

    Yes, but it also kinda depends on what happens at and after junction 34, from which point on more than the entire population of earth is at stake.

    If anything, this shows how ludicrously fast exponentials grow. At the start of the line it seems like there will be so many decisions to be made down the line, so there must be a psycho in there somewhere, right? But (assuming the game just ends after junction 34) you're actually just one of 34 people, and the chance of getting a psycho are virtually 0.

    Very interesting one!

    You gotta double it until it overflows to negatives, then you end up reviving billions of people!

    Continuously double it so that the trolley has as much room as it needs to brake to a complete halt, therefore killing 0 people.

    If I must kill 1 person or cause even more death, I suppose I'd kill the person responsible for this scenario.

    Double it. Then the other guy will double it, and so on. Infinite loop = no deaths.

    Loop continues until entire human population tied to track and there's nobody left to pass the switch to. kill the scapegoat on round one and done

    You would need a crazy low probability of a lunatic or a mass murderer being down the line to justify not to kill one person

    Edit: Sum(2^n (1-p)^(n-1) p) ~ Sum(2^n p) for p small. So you'd need a p= (2×2^32 -2) ~ 1/(8 billion) chance of catching a psycho for expected values to be equal. I.e. there is only a single person tops who would decide to kill all on earth.

    You don't even need a lunatic or mass murderer. As you say, the logical choice is to kill one person. For the next person, the logical choice is to kill two people, and so on.

    Well what about the fact that after 34 people the entire population is tied to the tracks. What are the chances that one person out of 35 wants to destroy humanity?

    Also thing the entire human population to the tracks is going to cause some major logistical problems, how are you going to feed them all?

    I say let it go for 33 doublings (2^33 people), and then decide.

    Throw the switch to pass and then sprint ahead 31 spots so I can kill 4 billion people like Thanos.

    People always miss the bigger picture with these things. Why do these trolleys' brakes keep failing? Is it a design flaw in the braking system? Is the maintenance crew severely underfunded? Is it a slippage problem due to improper rail maintenance? It's a shame we can't even organize a work stoppage to sort this out since congress blocked the trolley union from striking...

    Kill 1 person. I feel it would be cowardly to pass the buck and risk killing 2.
