"If we look at most current medical procedures, they are barbaric. Chopping stuff mainly." One has to agree with your view, at least partially. I've heard it said that surgeons are akin to carpenters—some are skilled craftsmen who craft fine furniture, others like builders whose skills are pretty much limited to joining bits of 2x4s but none of whom know the underlying mechanism of how trees grow or how they produce wood. Nevertheless, with the fusion of modern chemistry, a refined understanding of biological processes, and advanced computing and specialist manufacturing techniques (micro sensors etc.) we're just now beginning to see the end of some of the 'chopping'—or at least how in the future we might end it. I've been around for quite some decades so I'm unlikely to benefit from any new technique—they being too immature for deployment—but on current evidence those who are around in 50+ years are very likely to do so.
