Outside of some borderline cases like if you're from Ukraine or Iran or Afghanistan, economically you are better off than at any point in history. Climate change is a problem but finally people are admitting it's real and stepping up to the plate. Even oil and gas companies are getting into renewables and governments all over the world are subsidizing research on how we can help minimize climate change and also minimize the impacts of it.

As for AI, I create ai models for my job. People are wildly overblowing how powerful they are. They're very good at pattern recognition, but a level of ai that will come anywhere close to rivaling humans is centuries off imo, not years or decades. It's worth noting that most of what you said could have been said at any point in human history. I actually think you're missing something that's even a bigger deal than everything you put here, and that's potential nuclear war. Russia using one in desperation, Iran getting one and using it because they're a theocracy that is willing to die for an eternity in heaven, it just doesn't look great.

But for all of history, these things have been predicted. And for all of history, none of it happened. Maybe this time it's different, but probably not. Also even if it is, what do you gain by worrying about it? Unless you have a solution to any of those problems that no one else has thought of, you're only going to get depressed by thinking about that. Spend time enjoying your own life, finding meaning in your own life by creating connections with friends, family, and community, and only worry about things you have the power to change.
