scientific discoveries are always useful to us true or false
Answers
There is nothing good or bad about scientific discoveries, sooner or later new discoveries will occur, they are like knives, in the hand of a surgeon can save life, in the hand of a criminal can take lives!
Scientific discoveries unless purposefully created to do harm are neither good or bad; it depends on how the discoveries are used, and that is up to humans. For example the sciences of math, physics, engineering, statistics, are all involved in the increasing discoveries of AI, but there is currently a backlash on the harm that AI is doing and may be predicted to use. This is not because of the science of AI, it is because the algorithms build into the system are done by humans with their biases and lack of knowledge of the full scope of what they are doing.
