Why do you think that humans were brought into existence?

Good question. There is no correct answer, it's all subjective. But personally, I think that humans were brought here to ensure the earth's survival. Because human's have the mind capacity of all living organisms to build artificial intelligence, which in turn once they reach artificial super intelligence, then robots will be able to make themselves smarter, and with all of this extensive knowledge, they will be able to ensure that everything gets stable, and we don't use up all the non-renewable resources, we don't crash into a meteor, we don't die from a lack of oxygen... because artificial intelligence will ensure that this will not happen...

Pretty crazy, I know. But it's interesting! 

You don’t list any options but the one that frets overspending and the consequences of that.
