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?

Cultural values are, in themselves, neutral as well as universal, and so much depends on how individuals or ethnic groups use them. Values are influenced by so many factors such as geography, climate, religion, the economy and technology.

Society has to get a grip and put a tax on carbon. Of course, there is much that flows from that, and it is a complex situation. The small details of something such as climate change are political and social, and they are a lot about fairness and how we rebalance towards a fairer society.

Well, I think of the folks who are the climate deniers as the flat Earthers and the people who say the moon landings never happened.

If we talk about the environment, for example, we have to talk about environmental racism - about the fact that kids in South Central Los Angeles have a third of the lung capacity of kids in Santa Monica.
