Amazon's expansion into healthcare is already distressing patients and providers

Amazon and Google both seem to be speedrunning the usual corporate arc in which companies are founded on innovation, become wildly successful, and then spend decades on a profitable slow decline while they become more and more ossified and bureaucratic, ending in either acquisition or collapse.
