Are We Born Optimistic? Or Is It a Coping Skill We Learn as Adults? | Lori Markson

There’s one brain bias that affects 80% of adults and it has a familiar name you may not expect: optimism. Not always thought of as a cognitive mechanism, the optimism bias leads people to overestimate the likelihood of positive outcomes and to underestimate the likelihood of negative outcomes. It can be hugely helpful in our social lives and in keeping us motivated even if the trade off is, at times, the denial of reality. So where does this cognitive bias come from? Are we born with it, or do we develop it as we grow? Developmental psychologist Lori Markson compiles research about how optimism works in babies and young kids, and how that may help us to understand why we adults are the way we are.

The incredible inventions of intuitive AI | Maurice Conti

What do you get when you give a design tool a digital nervous system? Computers that improve our ability to think and imagine, and robotic systems that come up with (and build) radical new designs for bridges, cars, drones and much more — all by themselves. Take a tour of the Augmented Age with futurist Maurice Conti and preview a time when robots and humans will work side-by-side to accomplish things neither could do alone.

What intelligent machines can learn from a school of fish | Radhika Nagpal

Science fiction visions of the future show us AI built to replicate our way of thinking — but what if we modeled it instead on the other kinds of intelligence found in nature? Robotics engineer Radhika Nagpal studies the collective intelligence displayed by insects and fish schools, seeking to understand their rules of engagement. In a visionary talk, she presents her work creating artificial collective power and previews a future where swarms of robots work together to build flood barriers, pollinate crops, monitor coral reefs and form constellations of satellites.
