If science were about the simple things - like electrolysis of water, or making graphene - it would be okay for use in this life. But science is fill with all kinds of theories, some of which will never be able to be proven. What are the theories for? Two things:
1. To help build a product that they can sell and make money;
2. To find the answer to life, the universe, and everything = religious (42?).
In its simple ways, science is a tool. In its complex ways, science is a religion.
Science is not a religion. There is no dogma in science. If a theory doesn't fit the measurable facts, it is eventually discarded.
Right, pure science isn't but I think he's referring to personal bias that can bleed into research or people being influenced to do certain studies (and maybe change results here and there)... those kinds of things, tampering with the actual practice of science
