Your sarcasm is noted, but YES, the world does need high-IQ, high-conscientiousness people breeding far more than it needs low-IQ, low-conscientiousness people breeding.
Both of those traits are highly heritable, and both of those traits are going to be necessary to get this species off this rock rather than degenerating into watching reruns of "Ow, My Balls!" while energy supplies dwindle and climate change finishes us off.
Apparently modesty isn't that heritable. If you think the world's problems are going to be solved by your one wunderkind, rather than investing time and money in the already considerable number of intelligent people on the planet who are lacking opportunity, then clearly your genes aren't all that valuable.
We have enough people and our gene pool isn't diverse enough to make any one person invaluable to the future of the planet.
Good thing you don’t get to control who’s genes propagate and who’s don’t. All you can do is prevent your genes from being inherited. And, that is your sole prerogative. Just as spreading my genes, is mine.
So what is your goal? Your genes are in already loads of people. No matter how many kids you have your specific combination of them will be diluted out of existence in a few generations.
..
This is very hard to quantify and I certainly have no data to support this, but; I suppose, in this era of civilization, your actions in life, your influence on society and culture, and memes you propagate, rather than genes, will have a much greater influence.
