The world is changing, I don’t know what the future holds

In the last few years my perception of the future has changed. Five years ago I was optimistic about the future and I thought humanity was getting better. But now I’m not sure anymore. I see changes everywhere and it feels like everything is moving fast. I see AI, robots and automation replacing jobs. I see political polarization and social unrest. I see climate change and environmental disasters. I don’t know what the future holds for humanity. I don’t know if we will be better off. I don’t know if my children will have a bright future or if things will get worse. I’m scared. What are your thoughts?
