What is going on in this world now?!

To tell the truth, I'm in shock! We're living in the XXI (21st) century and we're smart human beings, with great technology. * Nevertheless, something is wrong with this world. It's seems like it's upside down. In all the mass medias * we hear the news like (as though) from a great blockbuster-wars, killing, terrorism... Whose script are we following? And why don't we enjoy our lives, as they are so short?...I'm terribly sorry for all these events...

* Technology is often treated as a collective noun. Technologies, on the other hand, are countable. This matter is subject to debate, but I think it is best to look at your larger context and consider whether you mean technology as a broader theme or specific technologies.

* Medium is the singular form of the word. Media is the plural form. In practice, we just say media.

It is an excellent essay. Best of luck to you!
