Some people make bizarre claims they're a scam, but (in addition to being libelous) that's as unsupportable as claiming now they will succeed.

My position is they're the least dubious of all the fusion efforts, and have a very clever design that offers the plausible possibility of avoiding some of the engineering and economic showstoppers confronting DT fusion. Of course no pudding can be eaten before it's cooked, and no reactor design can be counted on before it's proved.
