With the changing dynamics of AI and automation in healthcare, Doctors are left feeling a bit insecure. Working in a challenging environment of being replaced by machines.
Vinod Khosla, a Silicon Valley venture capitalist, says that the medical profession is approaching extinction and predicts that the majority of our work will eventually be outsourced to algorithms and other artificial tools of clinical reasoning.
He’s partly right. But I think my profession is heading to evolutionary change, not extinction.
Much of what we did with our eyes, hands, and ears have been replaced by machines. In my corner of the United States, a child who comes to an emergency department with abdominal pain is likely to have a CT scan before ever being examined by a physician. The stethoscope, the very tool that shaped and defined the bedside examination, began to be phased out as a way to explore the heart sometime at the end of the last century. Other more sensitive diagnostic modalities have dulled our capacity to understand and depend on what we see and hear.
As machines are replacing the medically mundane routines, we are entering a post-human era of medicine. In “The Innovator’s Prescription,” Clayton Christensen and Jason Hwang describe the landscape of medicine as evolving from one of intuitive guesswork and pattern recognition to one of precise, targeted medicine — care well-suited, it seems, for automation and artificial intelligence.
We probably can’t. So we need to start redefining what the human doctor of the 21st century will do.
Cleaning away work that is ‘no longer human.’
This redefinition is an important exercise for practicing physicians. It’s even more important for how we train the next generation. What will a doctor need to know or be able to do 20 years from now?
Medicine is changing faster than those charged with training doctors can keep up. Medical educators in the early 1990s wouldn’t have been able to foresee that medical imaging would replace the physical exam. The democratization of information brought by the internet and the unrestricted access to information by patients would have been considered heresy at the time. Our ability to predict the future course of medicine and the role of the physician in it is predictably poor.
There are certainties from which we can draw. Knowledge, for example, has expanded well beyond the scope of what anyone human can assimilate. So it’s likely that the next generation of doctors, instead of committing to memory, will access what they need to know.
In a brilliant stroke of irony, I suspect that it may be Khosla’s clinical machines that help us solve our professional dilemma. In his book, “The Most Human Human,” Brian Christian suggests that only through devices will we be able to understand what it is to be human. He describes the rise of artificial intelligence as a type of maggot therapy: It consumes only those portions of the physician’s work that are no longer human, restoring us to health.
A first analogy, to be sure, for a modern dilemma. But it’s an apt description.
Better put: If a machine can do it, then it was never really human, to begin with.
Perhaps the future will hold a role for physicians somewhere among the technologies that diagnose and target therapy. As the human body becomes digitized and quantified, there will be an emerging role in shaping individual human information as knowledge and wisdom. There will be an essential role for humans as docents that put the deluge of data and diagnostics into a broader human context.
Doctors need to embrace the machine
As medicine undergoes perhaps its most extreme transformation, physicians should be optimistic about the opportunity for redefinition. In the discussion about doctors and computers, there’s an assumption of inevitability that could be referred to as technological determinism. According to this theory, society’s technology determines its social structure and cultural values. Simply put, we follow the lead that technology appears to provide.
But instead of seeing ourselves as victims of the machine, we need to look at ourselves as active participants in not only shaping the future but defining our role before we arrive. Physicians have agency.
In their new book, “Machine, Platform, Crowd: Harnessing Our Digital Future”, MIT economists’ Andrew McAfee and Erik Brynjolfsson capture the emerging roles of humans with their question. It quotes, “So we should ask not ‘What will technology do for us?’ but rather ‘What do we want to do with technology?’ More than ever before, what matters is thinking deeply about what we want. Having more power and more choices means that our values are more important than ever.”
All of this starts with the recognition that physicians face a very different future. No matter what machines can and can’t do, the progression of technology calls upon us to undertake a critical rethinking of what we are doing now.
