Your arguments make sense in a way but I must disapprove your logic here.
What I don't understand in your reasoning is how can an individual decide for the mass, for 7 Billion people (and more billion more known life-form).
You are also omit a point, how can you be sure that people will not suffer more pain death than alive ? Your choice is around suffering, before "pushing the button", how can be sure that people will not suffer after death ? With this lack of knowledge how can you be sure that your choice will be the right one ?
When humanity will die out that history will be 'wasted' anyway. History does not have a purpose so I fail to see why it would matter when humanity ceased to be.
No history will not be wasted if humanity goes extinct, a lot of civilisations have been extinct, we still have informations about them, how they got extinct, their cultures, religions, some writings..
Another life form can still discover the ruins of our civilisation, and learn about it 50, 100 or 80 Million years after our extinction.
So even if humanity die out, that history will not be "wasted" it will still live on, our history would still be recorded and how can you know that humanity will even go extinct in the first place ?
Why would the formation of stars or the extinction of life forms have any bearing on this? Even the lives of those who went before us and whom we did not know personally have no real meaning for us.
Yes it has a meaning for us, how many people who died contributed in humanity ? By religious, cultural or scientific way ?
Given our history and the incredible amounts of bloodshed, needless cruelty and injustices on an unimaginable scale I'd say we as a species are a failure and deserve to perish. We've almost succeeded in making our planet unlivable for millions of our supposed 'fellow men and women'. Isn't humanity swell?
How can you say humanity deserve to perish ? Well we are still here.
Animals, even insect made an incredible amount of bloodshed very species in the universe have done so, for any reason (not always justified), again religious reasons, land control etc.. Its every developed living form nature to wage war and kill each other, this doesn't make us a failure.
Why always talk about the "negative" form of humanity and not what we have accomplished ?
You mention scientific advantages: to stay in the same field it's not hard to name dozens of scientific inventions that were later turned into weapons causing many millions if not billions of deaths in total.
It's the people who were behind and in control of those weapons that led to all those deaths.
Let's talk about the nuclear weapon a scientific weapon, one of the most cruel one, it was used against civilians two times in history. (Hiroshima and Nagasaki).
But thanks to them, the majority of the world is in peace and it will be for a long time even the world leaders you can think as crazy wouldn't push the nuke button ever again even the most suicidal one, the repercussions would be gigantic.
Humanity or even the human is a baby, we are still "primitive" in a certain way or on a big scale, we still have a lot to learn and we are learning. The future of humanity is bright.
We are just the result of 300.000 years of evolution, this is nothing, really nothing on a big scale we still have a long time ahead of us.
I know the 'you're worse than Hitler' argument is popular and sounds good but could you actually explain why that would be so?
I used it because when I was answering Nnana, he mentionned the Holocaust.
And comparing the holocaust with the complete
annihilation of the universe is still comparable.
It would be very close to Hitler, he lead to the extermination of 6M jews, by pushing the button someone would lead to the extermination 7B people, Billions of animals and I don't know how many Trillion of life-form.
In the end you would directly lead to the death of Trillions of life-form when you have the choice of not doing it.
For what reason ? Because people are suffering ? How can it be the reason of killing every single lifeform in the universe ?
Why would I be selfish enough to take the world away from people who want to live?
That's the word I have been searching for, selfishness.
How can someone be so selfish that if he had the choice, would eradicate every life-form because of his own psychology on the matter ?
