I thought I would not live enough to see such aberration

I do not see how it could be called an aberration, especially if you read and understood the article. We currently and regularly use stool and urine samples to detect many conditions; colon cancer, bacterial and viral infections, status of the individual's biome, blood, a variety of illicit drugs and medicines...a whole bunch of stuff.
This represents the possibility of doing many such tests simultaneously and, most importantly noninvasively and, potentially, at a much lower cost. I am not saying this particular product has been validated for much of anything and is ready for prime-time, but why look at it like a Luddite or as though it were some new-age nonsense?.
