The fact is that the world is developing at a frantic pace. Literally in a few years everything has changed beyond recognition.
Some people welcome the future and eagerly await the further development of mankind. These people believe that in the future life will be better and humanity will be able to overcome those difficulties that have arisen before it now.
Others believe that this will only worsen and that the development of mankind must be controlled. For example, cloning is forbidden by many religions, the morality of people. So many discoveries are forbidden, which can be done.
Personally, as for my opinion, I think that people were constantly afraid of something. Because of this, scientists and people were burned. They are afraid and therefore do nothing. As for me, it's stupid, because it's better to do and not to be afraid.
