We also didnt understand how the internet would change the world, still went ahead with it. We didnt understand how computers would change the world, still went ahead with it, we didnt understand how the steam engine would change the world… etc etc.

No one can know how a new invention will change things, but you are not going to be able to crush human’s innate creativity and drive to try new things. Sometimes those things are going to be a net negative and that’s bad, but the alternative is to insist nothing new is tried and thats A bad and B not possible.
