These concepts dealt with slicing, rather than splitting, the atom, which would have made virtual alchemy out of intractable power source problems that face mankind today. Splitting the atom was the concept behind the atom bomb, a runaway process resulting in uncontrollable heat and expansion - an explosion. Slicing is cold fission, which with proper know-how can transform base elements into their components and take advantage of their remarriage at a later point. Slicing is also the correct method of dispelling radioactivity, where the process is stopped after the slice, skipping the remarriage. Einstein knew that the blockade against these concepts reached outside of academia, as the energy cartels are some of the most powerful.
Concepts threatening wealthy cartels invoke government as well as industry response.
The bribe or threat is ever present, and takes many forms. Worse than an idea not born or promulgated is an idea countered, as countering does not simply deny, it constructs and preaches an alternative theory, which must then be overcome. Better to have the field free for the child to ponder, so that the next Einstein can emerge, as emerge he did. This time around the route was not on the international stage of academia and debate. This time around the bearer of this gift was a quiet man, also of Jewish heritage, a simple plumber and self-taught genius who nicely delivered the goods.
