I think, at the end of the century we'll have a generation of parents and a generation of children who won't have had the deep satisfactions of being parents and being children in the way that they might have and are going to spend a lot of time fretting and worrying and being hovered over for nothing. The question isn't so much "What will happen in the long run?" but "What's happening to people's lives right now?"

We don't measure the quality of our other relationships by how well the other person turns out, for instance whether my husband is a better person after 10 years than he was when I first met him.

The largest and most powerful computers are still no match for the smallest and weakest humans.

It's turns out to be much easier to simulate a grandmaster chess player than it is to simulate a 2-year-old.

Developmental scientists like me explore the basic science of learning by designing controlled experiments.

Teaching is a very effective way to get children to learn something specific - this tube squeaks, say, or a squish then a press then a pull causes the music to play. But it also makes children less likely to discover unexpected information and to draw unexpected conclusions.

Owning our past allows us to own our future.
