Google is reshuffling its AI leadership as Demis Hassabis steps away from day-to-day management of DeepMind to become chairman and Alphabet's chief scientist, while CTO Koray Kavukcuoglu takes operational control. Meanwhile, longtime chief scientist Jeff Dean and several prominent researchers are leaving to launch their own company. Axios reports: Hassabis will add the title of chief scientist for Google parent company Alphabet and also continue to lead Isomorphic Labs, the company's AI drug discovery spinoff. Koray Kavukcuoglu, the current chief technology officer of Google DeepMind will serve as senior VP of the unit, reporting to CEO Sundar Pichai. Dean, a 27-year Google veteran is starting Discovery Loop, an independent publicity benefit corporation in which Google will be an investor and cloud provider. Joining him in that effort are Google senior fellow Sanjay Ghemawat as well as Oriol Vinyals, a DeepMind VP and Quoc Le, a Google Brain co-founder. [...] In an interview with The New York Times, Dean indicated that leaving Google, a public company, gives him more leeway to focus on scientific discoveries associated with AI as well. "We might make decisions that are not necessarily in the company's purist financial interests," he told NYT. "I've been working towards AGI my whole life and now, like many of you, I feel it is close at hand," Hassabis wrote. "It's critical that we collectively get the next steps right to ensure this all goes well for humanity and we usher in an incredible new age of discovery and wonder." "With this backdrop, I've decided that now is the right time for me to hand over my day-to-day operational responsibilities at GDM, so that I have the time and space to focus on the big picture and help influence what is to come to the best of my ability"

"When a group of teenagers set out to hike British Columbia's famed Howe Sound Crest Trail in early July, Google Maps suggested the trek would take about five hours," reports SFGate. "Instead, the hike stretched deep into the night, leaving the group exhausted, dehydrated, injured and in need of a helicopter rescue..." Although the approximately 18-mile route with a 6,000-foot elevation gain can be completed by experienced trail runners in a day, search and rescue officials generally recommend hikers treat it as a two-day backpacking trip. The teenagers, all 17 years old, believed Google Maps' estimate that the route would take about five hours. The printed directions they were carrying, which were shared publicly by Lions Bay Search and Rescue, gave simple instructions for two legs of the trail, but didn't account for the terrain or elevation. "[Google Maps] is calculating the time that you're walking a straight road on pavement," [said Maria Masiar, training officer and search manager with Lions Bay Search and Rescue]. "When you get into outdoor terrain, that no longer holds true." Expecting only a short outing, each hiker carried about half a liter of water and limited food. There are no reliable water sources along the trail, meaning hikers must carry enough supplies for the entire route. As the group climbed, they began suffering from dehydration and muscle cramps but continued onward despite falling dramatically behind schedule. Eventually, the group made the decision to turn back and abandon making it to the end of the trail — and as the sun began to set and the group started to descend, fatigue took its toll. According to Masiar, members of the group had already stumbled and fallen several times while trying to race the coming dark, and only one hiker had a headlamp. Eventually, another hiker slipped about 10 feet off a boulder, injuring his tailbone badly enough that he could no longer continue. Search and rescue crews responded, ultimately evacuating him by helicopter.
