That kind of understanding is centuries away from now. There is a lot of hype about medical junk, but it is just that. In the real world, the medical field is a commercial enterprise. It has a 3 sigma standard when all real science requires 5 sigma results to publish or make a claim. The vast majority of medical research is cherry picked which is absolutely unscientific. Go through a major traumatic injury like I have with my spine and you'll learn just how little humans actually know how to diagnosis and work on.

Most of the hype is to get and justify grant proposals and to promote dubious commercial endeavors. We still can not even explain or synthesize life, and we've barely started to document a sizable chunk of our DNA. Like all the claims about fully mapping the human genome are crap. It is because they call a MASSIVE chunk of it junk DNA even when there is plenty of evidence otherwise.

Biology is actually the ultimate technology. Once fully understood and mastered it will displace nearly every piece of industrially produced technology of our stone age of silicon. Such a future is inevitable, if we survive, because it is the only way to be long term sustainable and in balance with the environment. When that happens, it will be a time when people live the longest lives possible for a human.
