Technological dissimilarities of computers

The commercial CPU cards (of industrial range) are as dissimilar as possible (also known as technological diversification)  

It must also involve the integration of processing units in analyzing common failure modes  

The dissimilarity of CPU cores is verified with the technical notes of suppliers, but there is no guarantee of their accuracy we have no way to verily this. Moreover, we do not really know how to measure a dissimilarity how far should we go  

The dissimilarity of the CPU cores remains an almost subjective soft aigumenf for the safety demonstratioa Discussions are on-going  

So far, the technical arguments have been in our favor different makers, different technology however, in the future, how can we continue to provide this dissimilarity with the monopolies of Intel or AMD
