Science is based on the possibility of objectivity, on the possibility of different people checking out for themselves the observations made by others. Without that possibility, there is no empirical principle capable of deciding between different arguments and theories.
As it turns out, what looks like science sometimes is not.
Pretty soon we'll have robots in our society, you're going to have a lot of automated processes that used to be done by people - this is happening. Society and technology is changing so fast, and the impact of the change on society and technology is global, not local.
If you publish a scientific paper it is very hard to start a nationwide debate about something. If you do this in a movie, you can start a debate. We like to create a bridge between those two worlds - film and science.
