What happens with Science Fiction?

This issue has anything to do with space colonization, however I
believe many in here got an oppinion about it.

What do you think about SF Science Fiction. I mean, do you have the
feeling Science Ficcion is not what it used to be?

I believe in the past SF in the past was really a fiction based in
scientifical facts. Today almost all science fiction is just
childish fantasies.

In the past one could "see the future" reading Science Fiction.

Today, however, we just see the crap of bad writers and biological
artificial realities, radioactive societies, drugs, guns and torture.

What happened? Why a bunch of people does not have a clue of science
hijacked our favorite fantasy readings? How we allowed to happen?

I would like to hear your oppinions, even if is not related with the
main line of this list.
