The benefits of a room temp super conductor mean that it would be produced at scale for price points well above standard. It's that big a deal in performance improvement.

The paper's method is fairly messy, low yield, and brand new... But it's also not that complex of metallurgy afaik. I would not be surprised to see iterations on method that scale well.

Regardless: if it's true then it proves it's possible... Which wasn't guaranteed until now.
