Evidently, the only thing it's good for is providing endless dribble for snake oil salesmen to scam people with. There is an endless barrage of "our latest and greatest magic just solved a problem" and when the dust settles it's always some combination of exaggeration, lies, misunderstanding, and stolen work.
Even from my very limited understanding of high level fusion related math, I can bet it's the same case here. At best they're not lying and they provided a proof for some old math theorem. What I know is that fusion isn't "one proven math problem away", and I bet even if they're not lying it will not help that much if at all.
