Wasn't the space shuttle and it's SRBs reusable?

In the sense that both were effectively rebuilt from almost-but-not-quite-scratch for each launch, yes.

Despite claims about the future, doesn't SpaceX also refurbish their SRBs between flights?

SpaceX's rockets are all-liquid fueled. SRB = solid rocket booster.

So they don't refurbish the liquid fuel engines?

Not significantly. And they've re-flown a bunch of them.

There was already a working program that had their funding axed: Here's a video from 1995: https://www.youtube.com/watch?v=wv9n9Casp1o. There were others too.

Yes, because it is incredibly hard to bring reusable rockets from concept to full execution.

The idea has been arouns for a long time and there have ben dozens of attempts of course, just as flying cars, autonomous cars, real A.I, space elevators.

Concept an execution are vastly different animals, it is at least 1000 times more difficult to achieve resuable rockets than to have the idea and at least 100 times more difficult than to try it.

It really isn't a working program if it's never going to have enough payload capacity to lift its own fuel to orbit. It's a shiny prototype of computer controlled autonomous stabilized flight, like SpaceX Grasshopper. But that's about it.

To answer your deleted question, there would be no point in listing their achievements for you because you're obviously determined to ignore them, and having them listed for you won't change that.
