I do not want to take away any positives from having kids; however, I do think we should strongly consider whether we would actually be good parents and if we would be able to prepare them to live in a world where the bar is raising exponentially. Even if we find fulfillment in children, I question if it is really the best option for them in the long-term or if we may be selfish in our desires to have them.
I think shrinking population is one thing I would like to see. Until we start moving to other planets, I do not see the benefits of a growing population. Many people still live in poverty and lack a good education, which I believe parenting has the most influence on.
