Don’t be so pessimistic. Every generation had it’s problems and we are still alive. People tend to think they and their situations are special. That’s not true.
People this days, especially the younger generations, are very pessimistic. They seem to not even try to have a good life since it will end soon it seems. This will cause a lot of brilliant minds to let their potential die slowly while realizing later in life they could have done better.
You have to understand one important thing: While a situation is bad there can still be a positive trend. Less people die of hunger, Corona killed significantly less people than the Spanish flu. Etc.
Even if the climate changes, somehow mankind will survive. AI want kill all jobs since AI doesn’t have hands. There is so much stuff outside that needs human intellect. Don’t let the media and zeitgeist let kill your intellect people. Be optimistic!
