Researchers across the world are revitalizing their interests in power grid technology and solving many electrical engineering problems that otherwise lay dormant for decades. To Cisco certified networking enthusiasts such as myself, one particularly interesting area of smart grid research is power packet routing. To the layman, this essentially combines the internet and electric power distribution, so your devices can be connected to the internet by simply being plugged in. This helps IoT devices quite a bit.
Our world does not need to deal with billions of hungry people. Instead humanity needs to ensure every last person on the planet is fully enabled to contribute their maximum potential because we need every one. With optimal contribution of net human potential, overpopulation doesn't burden us. It instead empowers us to reach our full potential.
A myriad of psychological and sociological challenges face us tomorrow, born out of a world where novelty is scarce, the prospect of individuality, outnumbered, faces sublimation and creativity wilts in terra cocta.
Obviously, we must move forward; our economy demands it. Yet, we need to keep a close eye on our trajectory. Total loss of the factors which fecundate and fertilize to cultivate seeds of creativity may leave us stranded and lost. We need to maintain diversity of thought, so that we can take advantage of the cross-pollination of ideas.
