Why is it so hard to make genuine friendships as an adult?

I think that's because so many seem to have changed these days. We have learned not to trust each other as a result of scammers, trolls, you name it, it has affected our society. So many changes took place when covid hit. It made everyone want to isolate themselves from everyone else. That did have an effect on our psyche. We learned that we cannot even trust our government. It had a domino effect so everyone is more or less isolating themselves from others and hiding behind tablets and cell phones. This is not a Brave New World but a strange new world and that's sad. No one wants to take the chance anymore of getting messed over.
