To be frank, the available evidence at the moment is pretty shaky. Derek Lowe here is pretty optimistic, but most of the comments I've seen from the superconductor folks are pretty pessimistic [1]--and given that Derek Lowe isn't in the field, I'm inclined to favor their views over his at this point.

The original articles are a pair of papers posted to arxiv in a field which I believe isn't well-known for arxiv publications, and most science journalism tends to wait for a peer-reviewed paper to come out in a notable journal before reporting on it. Although it has been reported by some specialized outlets already (a category which I'd include Derek Lowe's In The Pipeline).

[1] See, e.g., https://nitter.net/i/status/1686373516286005248, which goes into why even the recent theoretical-confirmation papers are unpersuasive to them.
