While sitting in the canteen overlooking the assembly lines, Musk explained that his reason for building rockets that could go to Mars was that it might be a way to preserve human consciousness in the event of a world war, asteroid strike, or civilization collapse. Hassabis told him to add another potential threat to the list: artificial intelligence. Machines could become superintelligent and surpass us mere mortals, -perhaps even decide to dispose of us. Musk paused silently for almost a minute as he processed this possibility. He decided that Hassabis might be right about the danger of AI, and promptly invested $5 million in DeepMind as a way to monitor what it was doing. Continued here The Myth of the "Next Einstein"    Einstein’s fame arose from a perfect storm of science, culture, and personality, says physicist Paul Halpern.

Will his ingenious contributions ever be surpassed? Is there anyone brilliant enough to complete his dream of a unified theory of nature? Despite being an accomplished physicist, Nobel laureate, and Renaissance man, Einstein’s sometime ally, sometime adversary Erwin Schrödinger never came close to Einstein’s fame internationally. If anything, his cat has taken all the glory—at least as a cultural meme. Continued here
