The transition of world agriculture from food grain to feed grains represents an...evil whose consequences may be far greater and longer lasting than any past examples of violence inflicted by men against thier fellow human beings.

How do we address network neutrality when the whole world is connected? How do we ensure governments don't purloin this for political purposes? It's already happening. Look at Russia on the American election. How do we protect data security when everyone's connected? Look what happened with the ransomware. How do we deal with cybercrime and cyberterrorism and the disruptions of the system? And we're seeing this every week now.

We are already producing enough food to feed the world. We already have technology in place that allows us to produce more than we can find a market for.

We are entering a new phase in human history - one in which fewer and fewer workers will be needed to produce the goods and services for the global population.

What's really clear to all of us in the business community is that GDP is slowing everywhere. And the reason is productivity has been declining now for 15 or 20 years all over the world. So we've got very high unemployment, and it's structural. And it's compounded by real-time climate change - that's really a game changer.

Many of the genetically modified foods will be safe, I'm sure. Will most of them be safe? Nobody knows.
