It's much like neuroscience. We can say a lot about what individual cells and molecules do and how they interact with other cells and molecules. And yet, when it comes to actually modifying or changing anything, we're mostly hopelessly lost and nearly all of our solutions are of the variety: "put this drug into the bloodstream and see what happens, oops, that didn't work and took 5 years to complete trials, time to try the next one". The complexity is immense in biology and medicine and we have a hard time dealing with any of it in a meaningful way, other than to present extremely vague theories without practical use (like talking about "prediction" and "Markov blankets" in neuroscience, the "discontinuity" theory of immunity, etc.
