The very notion that millions of workers displaced by the re-engineering and automation of the agricultural, manufacturing, and service sectors can be retrained to be scientists, engineers, technicians, executives, consultants, teachers, lawyers and the like, and then somehow find the appropriate number of job openings in the very narrow high-tech sector, seems at best a pipe dream, and at worst a delusion.

In this country, the health concerns and the environmental concerns are as deep as in Europe. All the surveys show that. But here, we didn't have the cultural dimension. This is a fast-food culture.

Being both entrepreneurial and social is no longer an oxymoron, but rather a tautology.

Back in 1983, the United States government approved the release of the first genetically modified organism. In this case, it was a bacteria that prevents frost on food crops.

If I were Mark Zuckerberg or any of these guys, I would say, "My God. How does the world expect us to deal with this?" I mean, it's too big a responsibility; I think they're going to welcome this. They'll maybe keep it in the private sector, but they'll welcome some form of regulatory operation because they've been so successful that they are a global, public good. Everyone needs them.

Europe will not accept genetically modified foods. It doesn't make any difference in the final analysis what Brussels does, what Washington does, or what the World Trade Organization does.

Starvation does not occur because of a world food shortage. If everyone ate a vegetarian, or better still, a vegan diet there would be enough food for everyone. The only sane way forward is to grow food for humans rather than to feed it to farmed animals.
