But the details is biology. If we really understood biology, or even just precisely what aspects of a given phenomenon we need to investigate and how in order to understand it, we wouldn't have wasted a decade trying to reduce CVD by increasing HDL. Billions of dollars wouldn't have been wasted chasing the wrong mechanistic hypotheses in Alzheimer's treatment. Cancer would have already been sorted. Since 15 years ago, extracellular vesicles went from particles used to export rubbish from cells, perhaps with some vague immune involvement, to one of the fundamental mechanisms involved in intercellular communication, carrying nucleic acids between cells. The reality is the more we understand in biology, the larger we realise biology is and the relative amount of information that still needs to be figured out doesn't change much - especially when you look at it in terms of labour required, because what left is progressively less-low hanging fruit.
