Young cosmologists learn fairly quickly that engaging with eccentrics and their pet theories is generally not a good use of their time. My own experience is that "independent investigators" are almost always courteous, decent people. However, they appear to enjoy dissent as much as they enjoy grappling with the deep problems of physics. Consequently, they are rarely overtly upset that they cannot change the opinions of mainstream scientists, and will hold on to their positions in the face of overwhelming evidence to the contrary. The advice I give my students is not to wrestle a pig; you both get muddy, but the pig enjoys it.

As for me, I can see plenty of dangers associated with giving children wireless devices, but they are of the "why don't you get up off the couch / visit a friend / go swimming / throw a ball / practice your instrument / build something / ride your bike / read a book / do what kids did when I was a kid" variety.
Statistical reasoning is a double-edged tool: it lets scientists sift useful knowledge from the noise of the world, but in other hands it becomes a device for separating the credulous from their cash.
So, my take is that even if you can generate a spacewarp in the lab, a quick estimate says its gravitational effects would be billions or trillions of times below the threshold of detectability. The problem is not that warp drives are impossible, but that this description of them does not seem to be self-consistent.
Just when I thought the Weinstein/Einstein kerfuffle had wound down, it seems to have decided to go another round.
