How long do you suppose it will take for religion in general to die?

I guess it will happen gradually as individuals choose not to go along with it or not accept an authority over them . But there are an awful lot of individuals out there in the world living according to a religion so it could take a very long time. I think that science does not disprove a God though. Also, morality and humanitarianism could be failing too in a world where decisions including democratic and equal rights are based on economic outcomes/profits.
