If everyone thought like you then there would be no future as humanity would go extinct. It only takes one generation of everyone subscribing to your philosophy to kill us all versus the uncertain future of climate change, where there is no scientific evidence that we will all die. Unfortunately, too many people in the West think like you, which is why overpopulation isn't a problem in the West; in fact, the reverse is and governments are covering it up by increasing immigration. If you're concerned about overpopulation on a global scale, you better be prepared to address it (possibly violently) in Asia and Africa.

Unless you are an Einstein-level genius (who by the way, had kids), the best contribution you can make to society is to have kids. Kids are multipliers as their achievements can not exist if they are not born. There is no "experience" that is worth dooming humanity to extinction, and I also doubt you can name any experience that a parent has not had at some point in their life.
