It really seems like some decades in the future we'll look back at the results of gut microbiome research as akin to the discoveries of bacteria and viruses. Before those discoveries it was known that people got sick, and that developing sickness was correlated with various things, like proximity to sick people, or poor hygiene, but the mechanisms behind those correlations weren't known. (Or they were suspected, but with some misconceptions or lack of detail.) I expect and certainly hope that as this system is better understood, it will unlock numerous significant advances in medical science. Would just be nice if that process could happen faster!
