The Dollar?

Not sure if this is the right place.....

Should I be legitimately worried about having my assets primarily in the US Dollar? With the stimulus/bailout/massive printing of money by Fed everyone is talking about the long-term consequences of inflation and the debasement of the dollar.

Is there a real need to be worried right now or will the effects only play out in the long-term future?

Should I put money in hard assets/precious metals or what
