Given the sheer number of headlines like "<This invention> will change the face of <this well known thing>" that really boil down to "<This idea, which isn't even new> is interesting to think about, but won't really have any impact on <this well known thing>"... it really doesn't make one ill-tempered to bring up for discussion whether the current article is one of those.

It might not be one of those, and it's not fair to assume it _is_ one of those... but discussing whether it is or not isn't rude/mean, and probably _should_ be standard practice.
