People wonder about the long range effects of things because we can’t know them until a long time has passed. Like when the internet first became available in homes, we all had no idea that it would change society and even human psychology in the ways that it has. Do you never read about something that’s fairly new and think, “I wonder how that’s going to play out”? There’s not currently any answer as to what new information will be revealed or what new understanding will be gained over decades to come. Only time will show us that.
