That's not at all what I am doing, or what scientists and engineers do. We are all trained to think about ethics and seek ethical approval because even if knowledge itself is morally neutral the methods to obtain that knowledge can be truly unhinged.
Scientific facts are not a cultural facet. A device built using scientific knowledge is also a product of the culture that built it. Technology stands between objective science and subjective needs and culture. Technology generally serves some form of purpose.
Here is an example: Heavier than air flight is a possibility because of the laws of physics. A Boeing 737 is a specific product of both those laws of physics and of USA culture. It's purpose is to get people and things to places, and to make Boeing the company money.
LLMs can be used for good and ill. People have argued they use too much energy for what they do. I would say that depends on where you get your energy from.
