I'm surprised you took away from this that I think the goal should be making more humans because that's not what I believe and not what was I was trying to communicate. I don't think there is one "goal" to life and this article was in now way about goals but I'm glad you have such a sense of purpose for your life! I wish you well in that too!
Just because you mention it though - its a false dichotomy that creating more lives is at odds with improving the lives of the current existing people.
