Can we not get use out of them now though in data centers and as coprocessors for specialized devices?

  No we cannot, and we are very far away from that point. Eventually we probably will, but we are like 20 years away from that at least. And even if we can, its unclear how useful it would be except in very specialized situations.

  Right now, the most you could get from any existing QC in terms of practical every-day results is perhaps a good RNG - but there are far cheaper ones that are much more than good enough. Otherwise, the state of the art is using existing QCs to find the prime factors of 21 with probability >66%. The current huge value of QCs is in research into QC itself - we are very far from any practical applications.
