I find that a paradigm shift takes place in two ways. First, for all scientists to start working on the new paradigm like happened with Newtonian physics, it takes a long time. But there is another way where a group of people hang onto a model that they are all happy with and they are all finding new problems to work on within that model. For me that model has been that consciousness is the ground of being and now, lots of people are accepting that model. This is a great achievement. This change has happened in less than three generations. That's a tremendous achievement. Old paradigmers, like some of my colleagues from the U of O physics department, will take a long time to change.
