""We have absolutely nothing against bricklayers," Pivac says. "The problem is the average age of bricklayers is going up and it's difficult to attract new young people to the trade." There's a debate on about the future of automation-what it means that machines may be able to match humans at virtually any task. For now, robots are nowhere near that advanced."

"Now, by my estimates, the half-life of a career is about 10 years. I expect that it will decrease, within a decade, to five years. Advancing technologies will cause so much disruption to almost every industry that entire professions will disappear. And then, in about 15-20 years from now, we will be facing a jobless future, in which most jobs are done by machines and the cost of basic necessities such as food, energy and health care is negligible - just as the costs of cellphone communications and information are today. "

"One of the most mind-bending far future predictions you'll hear from some futurists is this: Eventually, the technology will exist to copy your brain (every bit of data that makes you, you) onto a computer. Technical details and exact predictions aside (the concept is still firmly science fiction) mind uploading makes for a fascinating and disturbing thought experiment. If you had the power to upload yourself, would you?"

"What if technology provided the ultimate resolution of this existential crisis by allowing you to plug your brain into a boundless, cognitive melting pot with other humans?"

"Recent experiments suggest AI peer reviews tend to be surprisingly good, with 82.4% of scientists finding AI peer reviews more useful than at least some of the human reviews they received from on a paper, and other work suggests AI is reasonably good at spotting errors, though not as good as humans, yet. Regardless of how good AI gets, the scientific publishing system was not made to support AI writers writing to AI reviews for AI opinions for papers later summarized by AI. The system is going to break."

"Sounds lovely. But a few (mostly worried) thoughts come instantly to mind. First, our fingerprints are unique whether or not they're attached to our hand. That sounds like a dangerous incentive to chop off a few fingers, no?"

"As smart as they are, doctors can't compete with the volume of knowledge that a robot can retain. In an effort to join the best of both worlds - human experience with robotic data - a number of companies are developing telemedicine robots that not only allow doctors to reach out to patients miles or continents away, but can offer immediate information and advice that draws from volumes of medical research and case studies. In January the FDA approved the telepresence platform RP-Vita, developed by iRobot and InTouch Health. Now seven hospitals across North America have enlisted the services of RP-Vita, bringing us one step closer to robotics-augmented healthcare."
