The world is always changing, and I am surprisingly generally rather happy with the changes I see.
Are you a troll?
Well I don't feel particularly trollish. Perhaps being generally optimistic (and a bit too ready to jump when someone makes big claims without evidence) is what defines a troll?
In general, my take on the world is that it is constantly getting better, while sitting on top of a volcano that might or might not explode (i.e. a metaphor for AGW). Politically and socially we are generally moving in the right direction even if the current lancing of boils makes it difficult to believe.
The world is more peaceful, more people live decent lives than ever before, fewer people get killed violently than ever before etc. etc. (the USA is of course an outlier and has always been).
We are living through a real and profound revolution in communications which will have a huge effect (as have earlier communications revolutions), scientific discoveries are coming in at a strongly accelerating rate etc. etc.
And yes, over the entire thing hangs the sword of Damocles (another metaphor for AGW) and it's not to be ignored. But at the same time, life goes on, and the world is happily changing.
