It will have its problems, but most likely will be more prosperous and less apocalyptic than we imagine.

Collapse: while there might be periods of difficulty, modern life won’t stop and we won’t be going back to the stone age or something.

Climate change: we’ll likely supplement our insufficient social and behavioral interventions with engineering ones once problems become too acute/expensive to ignore (i.e. soon).

Economy: recessions are a normal part of the business cycle. They happen every 10-20 years. We’ll survive, and the deeper the stock market falls, the better deals you will get coming in as a long term investor. Don’t let people talk you into never investing out of fear. You’ll regret it when you get older.

AI: It’s a historic revolution in tools and we’re in for the ride. Even if humanity were to end in favor of AI (Unlikely), AIs would basically be our descendants.

Bottom line: while you should care about these issues, you should not stress about them so much it detracts from living your everyday life.
