In logic: that some science is useful and beneficial to humans does not imply that all science is useful and beneficial.
Science is not and cannot be conflated with technology. Science is a method and an institution. It may use technology or be instrumental in invention and development of technology. But it is not and cannot BE technology. Your argument asserting validity of all science because it was responsible for devising some principles of light and optics through lenses is NOT an argument which can be used reasonably or logically to support ALL science and ALL of its subsequent developments.
Ethics in science and the politicisation and corporatism of science as an institution MUST now be factored in any rational discourse on the state of modern science.
