If we can learn anything from history, and if humans have proved anything over the last few thousand years, it's that we're incredibly adaptable to changing circumstances, and that we can engineer solutions to any crisis. Yes, there are problems, but for every problem the world faces, there's people working on solutions, and they will solve the problems, you bet. Why? Because why wouldn't they want to solve the problems and live in a better world? (Also there's potloads of money to be made in fixing problems like these.) Don't worry - the future is going to be awesome, be happy that you get to go along for the ride.
The future may be awesome for some people. The problem I have with such linear, inevitable-progress thinking is that that is not how history has gone. There are indeed people working on these problems, but the solutions they come up with might not be universally good for everyone.
Take the European invasion of the Americas. Most people think that was ultimately a positive step. Sure, they will regret the loss of some Native Americans, but ultimately they will say it was Progress. What a lot of people don't realize is that that progress required the deaths of millions and millions of people. Most people have the idea that there were very few Native Americans when the Europeans arrived, but 20th and 21st century scholars, with access to more information and more accurate projection models, have increased their estimates to where they suspect there were between 50 million and 100 million, if not more. This means that there would be a comparable number of people in the Americas to how many there were in Europe around the time of the Conquest. In 2006, the total population of American Indians and Native Alaskans was estimated at about 4.5 million. The destruction is on par with the Holocaust and Stalin's Purges.
One final note on this subject: when Columbus, who is generally regarded as a fairly neutral historical figure--great accomplishment, a few personal faults--arrived in the New World and established a European fort, he had his soldiers enslave and brutalize the natives, who had no weapons and had lived in peace for as long as anyone could remember. The Spanish were unbelievably cruel to the natives, working them death in mines, throwing their babies to hungry dogs, and things that seem almost beyond belief. Between Spanish cruelty, brutal conditions, suicide of the natives to escape the misery, and smallpox, the native population on the island the Spanish had landed on went from possibly as high as 1,000,000 (some scholars estimate it as high as 8,000,000) to 0 in about 30 years. This was what happened from a single European settlement.
Let's take some more modern examples. Europe and the US are pretty much considered the richest and most powerful countries in the world. The people who live in these places, by and large, believe that since they live such great lives, the rest of the world lives pretty great lives too, or at least their lives are better than were earlier. There are some places, like Africa and South America, where there are lots of poor people and lots of violence, but that's stuff they brought on themselves. As far as Middle Eastern terrorists go, people wonder "why do they hate us?"
Every single one of these places--Africa, South America, and Middle Eastern countries like Iran--has been ravaged by European and US meddling. Look up 'Covert United States foreign regime change actions' on Wikipedia and you will see just how many times the US has covertly overthrown foreign governments, many of them democratically elected governments. And each and every one of these places is now either a hotbed of poverty and violence, or absolutely hates the US. There were old Kingdoms in Africa whose accomplishments rivaled any European kingdoms or nations, until they were violently colonized by Europe long ago, and then suffered from Soviet covert actions. In all these places, the conquerers have extracted money and resources while the natives were left to starve and fight among themselves for what little remained.
My point here is that, while in the US and Europe, we are living in what must surely seem like a Golden Age--technology, medicine, entertainment, safety, etc--this golden age was built using things that were stolen from other people, who are now living amidst poverty and violence. The Progress that we see in the US did not come from nothing, and it did not come just from our brilliance and imagination--it was stolen from others. Goverments and countries have been overthrown repeatedly just so we can get cheap bananas in the US! And so US banana companies can get rich selling them. We have created a new Dark Age across large sections of this planet by destroying their societies and plunging them into chaos. You think the US economic crisis is bad? It is nothing compared to what has existed for generations in much of the rest of the world.
The solution that has lead to our current Golden Age was to take by force from other people.
