We're fortunate enough to live on a planet that's bathed in thousands of times more energy than we use and that's stocked with thousands of times more water, raw materials, and even food-growing potential than we need.

AI does not keep me up at night. Almost no one is working on conscious machines. Deep learning algorithms, or Google search, or Facebook personalization, or Siri or self driving cars or Watson, those have the same relationship to conscious machines as a toaster does to a chess-playing computer.

Neural implants could accomplish things no external interface could: Virtual and augmented reality with all five senses; augmentation of human memory, attention, and learning speed; even multi-sense telepathy - sharing what we see, hear, touch, and even perhaps what we think and feel with others.

Everything good and bad about technology would be magnified by implanting it deep in brains. Is the risk of brain-hacking outweighed by the societal benefits of faster, deeper communication, and the ability to augment our own intelligence?

Japan's experience suggests the importance of assessing the sustainability of price stability over a fairly long period, which many central banks have emphasized in recent years.

Healthy forests and wetlands stand sentry against the dangers of climate change, absorbing carbon dioxide from the atmosphere and locking it away in plants, root systems and soil.

We're really going after truly creating sustainability of a disease-free state, creating a complete system for managing cancer patients for life, so that you can manage from onset of disease all the way through.

We have made great strides, but somehow we've got to create a climate so that everybody can do well, not just some.
