If we're talking about future humans, we get into the exponential growth stage pretty quickly.
You have 2 kids, and they each average 2 kids, and they each average 2 kids, etc, etc
2, 4, 8, 16, etc - 2 ^ n where n is number of generations
After 20 generations we're already talking a million descendants. With a rough range of 20 years per generation we get 400 years.
That number only blows up from there. In 30 generations we're at a billion in 600 years.
One minor decision whether to take a train or a bus or what have you can have wide ranging effects on potentially billions of humans far into the future. It's a bit absurd thinking about it. Everything you do has potential to radically change the future. Of course, your family line could just as well die out with you.
Now imagine how many descendants you have in your family tree going all the way back to the cavemen. Think of how many infinite little decisions led to the chances of your dad fucking your mom on that specific minute of that specific day. It's effectively a 10 ^ -โ chance of you being born. And yet you're still here.
