Just temper your expectations a bit and don't get hyped up by people on the internet. All of these are exciting developments, but no one is going to know the truth of it until you have multiple independent confirmations in one direction or another. No single piece of evidence is going to be convincing unless it comes from one of the big labs, and they're unlikely to publish quickly because they're going to wait until they have to k solid proof.

As someone with experience working on superconductors, the DFT results and this paper are exciting because they show that at the very least this is likely a new class of superconducting materials at least as good as the current industrial ones. Knowing that the authors are on to something and that the initial claims aren't totally nuts is exciting and fun to post about, but it'll take time to be sure about any of this.
