One could argue that practical (i.e. with a net energy gain) nuclear 
fusion already is a fact. Stars do it, and even humans (albeit in very 
limited ways so far). By contrast, at least as far as I'm aware, there's 
no example of practical quantum computing, and it may be that it's 
fundamentally impossible.
