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

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

[–] ghariksforge@lemmy.world 9 points 2 years ago (2 children)

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.

You could just move them over whenever someone decides to double it up. That way the person that was going to die alone is doomed to die anyway. 😂

I wonder if we do stack it till every human is tied to the track whos at the lever?

Does the train/AI decide?

The current version of GPT is willing to sacrifice billions of robots for humanities sake. However, it proposed to strap alien civilizations to the track next. And in that case it would choose to save the larger group…

It'll just be one fewer junctions. 2^n is always one more than the sum of 2^1+...2^(n-1)

[–] Magikjak@lemmy.world 1 points 2 years ago

I think you have to include 2^0 for that to be true?

e.g 2^0 = 1, 2^1 = 2 2^0 + 2^1 = 1 + 2 = 3, 2^2 = 4 … 7, 8 15,16 31, 32 etc.

2^33 is approximately 8.5 billion, which is roughly the population of the world.

So the 32nd person decides to either kill half of humanity and end the scenario, or give someone the power to end human kind...

And then there are only 32 people who will live. Trolley doesn't have a driver i imagine, they died of a heart attack or something.
