“”I’m interested in the policies that prevent us from providing
an education to anyone in the world who might want one,” Green
said. That worldwide demand for education outpaces our ability to
meet it.One in seven people on the planet don’t get enough food, a fact
that led Green to ask whether, if we had a machine that could feed
everyone with a marginal cost of zero, and no ill effects to
farmers, should we turn on the food machine? The obvious answer
seems to be yes–and Green says that while we don’t have a food
machine, we do have a learning machine. But without policies–open
policies–we can’t turn it on.
