I think it's sort of a natural thing. Every generation thinks that the end of the world is going to happen within their lifetime. It's only natural that they extend that to other things.
I think it's stupid, but we do have a tendency to focus on the negative things in life.
Increased gas prices? World's gonna end. People fighting a war? World's gonna end? Some radio dude says the rapture is just around the corner? By Jove, he must be right! ...Oops, doesn't look like it this time, pal.
If anything affects society in a way that some people view as negtive, they'll always criticize it and try to say that it's a problem and things need to be done about it. Sometimes though, it's not the people, but the companies themselves.
With a smaller number of smaller companies putting games out because of mergers, buyouts, and other things, a lot of games have a same-ish feel to them that's allowed a lot of gamers (myself included) to be unenthused about many recent games. Marketing games to a larger audience makes those niche gamers (again, including myself) even less enthused about the gaming future.
It's not just games, either. Look at some of the major company problems in the last few years.
Toyota's car problems, the off shore drilling problem, skyrocketing gas prices (thankfully that seems to have stopped for a bit), recalls by tons of toy manufacturers because of health concerns, recalls of cribs because of baby deaths, and a great many others.
Life's tough, sure, it'll end some day, but there's not a whole lot we'll be able to do about it, so why worry? XD
