While some are claiming this means things like warp drive [...] are right on the horizon
Who are these "some"? The article linked to by the sentence makes no mention of any claims of it being a warp drive.
And then this from the Forbes article:
When you come across an announcement like the one made by NASA Spaceflight a week ago: that NASA has made a successful test of the EM Drive — a propulsion engine that uses no propellant, seemingly violating one of the most fundamental laws of physics, while warping space in the process — you’d better make sure you aren’t fooling yourself.
The linked announcement makes no mention of warping space, so the bolded section seems inaccurately disparaging.
It sounds to me like the guy who wrote the article has fooled himself into believing that someone has claimed it's a warp drive for the purpose of being able to find something to write indignantly about.
Come to think of it, the writer doesn't even seem to be sure of who's who in this scenario. "When you come across an announcement [...] you'd better make sure you aren't fooling yourself." Why would I be fooling myself by simply reading an announcement? Surely it's the people who make the announcement that should make sure they're not fooling themselves. Which I might think they were, if they'd said anything about warping space. Which they didn't.
So just who are these apparently imaginary people that the summary/article is railing against?
