What if robots took over the world?

It’s been quite a while since I’ve read Dune. I found my way to this interesting conceptualization, Sietch Nevada, through my regular StumbleUpon clicking. For those not familiar with Dune by Frank Herbert, please check it out! It is an excellent novel, as described in my review. I find it interesting how many ideas are drawn from Sci-Fi. Everyday technology like cell phones, video conferencing, and robots (well maybe not everyday yet), were hinted to by authors long before they were developed. I find the Sietch concept intriguing because I lived in Phoenix, AZ for many years. A few years after I left, I started hearing about how Lake Powell, fed by the Colorado River, might dry up soon. I thought that it meant there would be no more water, but experts are referring to “dry” as unable to generate hydroelectric power. So, not only will water levels be low, but there could be power shortages as well!
