Educational Blocks - If it is so amazing, why is it not used by someone?

When I discuss the existence of great unused inventions and the contents of this blog with people I am often met with the statement: "If it is so amazing, why is it not used by someone?" This phrase is so common that it almost seems like a response running on default, like the memes I wrote about earlier.

Where does this instant rejection of the amazing possibility of a breakthrough for mankind come from? If you were drowning, would you not least attempt to reach a floating object? It does not seem to be the case with long term hazards caused by pollution, wasteful energy sources, overproduction, hunger etc. When I attempt to dig in why my (of different backgrounds) debaters are sceptical towards investigating the integrity of claims on great breakthroughs, and I usually get a school/high school quote of sorts. Examples could be "my physics teacher always said engines can never produce more energy than they can consume and that it is simply impossible" or " it is against the laws of science - so I can not be". I was told these things too, and in a discussion they are statements that are hardly open for discussion. When I try to list some of the problems a good invention might meet before it is on the supermarket shelf, the most difficult to believe is the inventions design - not the problems it faces. I do not like conspiracy theories (though this blog might be labeled as one), but is it not scary that individual thoughts can get one tracked like this? Should we curiosity not be allowed to overcome scepticism in the case of need?

In my own opinion I did rather poorly in school until I realized that I was complicating things by taking too many variables into account at the same time when solving an assignment. My teachers, who I respect, did not want my interpretation or creativity so much as they wanted the correct answer. All through my education, up to doctoral level, I have been schooled in searching for answers that fit the mental box called facts. I agree this reality works very well per default - but it may restrain you and me from even accepting the existence of a revolutionary technological breakthrough. And how do you approach that as an inventor? It works, you can show it works, but people deny it because they have been taught I can not exist. If that is the case perhaps technological breakthroughs are left to be investigated by believers who can accept humanity might not know everything, but can hit a lucky strike when trying to reach for the sky.
