Hmm, what is implausable and what is plausable? Those border move forward as our civilization move forward and our understanding of science grows more advanced. A flying machine to the ancient Greeks was implausible, to Leonardo Da Vinci it was plausible, and to us it is a dayli day item, broadly understood by most.
Newtonian physics ruled until quite recently, many thing indicate that the rules does not work on a Galactic scale and other things influence heavily, unfortunately most is still just theories, we just yet have not the tech to prove or disprove. It is doubtful that we might ever get a full understanding of the Universe.
Just as the old "God" question, we seek answers but none to be found. None can be dis proven and none can be proven.
There is no doubt that the thoughts of the people in the interview are a contributing factor to thinking out of the box, which is what is needed, then followed by an scientific approach to prove theories.
The big hindrance to general progress in these areas is more likely to be due to an ingrained superstition still abundant in the general populace.
It is, at the moment , as we have passed a scientific zenith, and are on the route to a New Age nadir.
The recent changes (08.11.2016) in one of the most influential countries in the world was a potent indication of this trend. Science denial is not new, it is an old phenomenon, mainly contributed by the fact that advanced science is like magic to the uninitiated.
(Thought advanced by I, Asimov in Foundation series book 3 I think)
If this mindset grabs hold, it will take some time before we get back on track.
I am perfectly aware of thinkers like Neil Degrasse Tyson, Stephen Hawkins and innovators like Elon Musk, jeff Bezos, but will it be enough?
(many others in fact)
