How long will it be before society views brainwashing children with creationism as harmful?

To brainwash children to believe creationism in place of modern science is harming them. It’s harming their ability to contribute to society; it’s poisoning the intellectual well. I’m sure that future society will punish parents and teachers who brainwash children with creationism but I’m not sure how long it’s going to take before we see laws regarding this. How long do you think?
