24 years ago I had life-saving heart surgery. The treatment was not available to my grandmother who had the genes from which I inherited the condition. She died very young, but that was normal in her time, there was no treatment for this kind of disease beyond, don't exert yourself too much for the rest of your (short) life. Do you think heart surgeons are less useful now that we've had such amazing innovation in one freaking lifetime? Right now we're just beginning to discover new ways AI gives us the same kind of new power that bypass surgery gave to surgeons. #
