You're trolling, right? In case you're serious;
You don't seem to realize that all the major issues that people face stem directly from overpopulation. All of the real modern challenges are issues of scale. Energy scarcity, food scarcity, transportation complexity, pollution levels, disease susceptibility, psychological disorder, climate change, and political unrest are all directly related to the number of people on the planet. While you, (and all parents, regardless of species) get a warm fuzzy feeling in your tummy about your offspring, the fact remains that humans are too reproductively successful to continue at our current pace. A person who relegates their occupation to "caregiver" is short-sighted and is merely passing the buck to the next generation. Unfortunately, because of our natural reproductive instincts, this generation will be larger, and their problems will be compound.
I work in the field of robotics. It's exciting, but it's in its infancy. Robots are very very far from solving the world's problems. I imagine the same is true with GMO crops, robot general warlords, and whatever other tech hype you've been reading about. To envision these nascent technologies as humanity's salvation is to ignore the real problem: There are too many of us.
