Will the era of liquid fuel for rockets ever end?

Is it true that we are still useing the same liquid hydrogen fuel mixture since the space program began in the 1950's?

Now I have to assume that fuel for modern rockets is far more sophisticated, but shouldn't we he have nuclear propulsion by now?

Cost should not be an issue, because NASA gets alot of money from the government. And we have several different types of other vehicles that are propelled by nuclear reactors.

Nuclear propulsion seems safer than what we have today. And we could probably achieve higher speeds in space as well.
