The Replacement for PCR Tests Has Arrived - promising, but I am not convinced:

Ironically, I recognize the underlying problem. I was supposed to solve it during my second PhD. Back then, in 2014, I came up with a partial solution to this related problem (DNA authentication). Technically speaking, the problem cannot be solved. My former university turned some of my ideas into a patent. Nonetheless, I am afraid it ain’t as easy, let alone for in vivo applications, as would be required (see the video).

Moreover, I wonder if we should “treat patients for cancers they don’t know they have.” The idea presented is to eradicate all mutations, as they are present in low quantities. But how would we know which of these could end up being relevant enough to cause disease? Do we have to attack everything, and, thereby, do WHAT to the organism???? Somehow, this premise reminds me of trying to get rid of all bugs. Yet, we neither live in a bug-free universe, nor do we have only perfect genes, according to our definition. It raises the question of which roles are played by objects we commonly assign a negative trait to. See, e.g., living in a sterile world.
