It starts like any routine diagnostic moment: a seasoned pulmonologist, eyes locked on a chest X-ray, deciphering shadows and streaks with the confidence of someone who has spent over two decades learning to read them like a map. But in the blink of an eye, a new competitor enters—not a younger doctor, not even a human, but a silent, calculating intelligence trained on millions of images. And it arrives at the same diagnosis in seconds.
Dr. Fawzi Katranji, a U.S.-based pulmonologist, captured this eerie moment in a TikTok video that’s now making waves. The caption reads bluntly: “I’m going to lose my job.” In the clip, he walks viewers through how he would traditionally analyze a complex chest X-ray—spotting pneumonia patterns, consolidations, and reading subtle cues that, for decades, have defined the art of his profession. But then he turns to Lunit INSIGHT CXR, an AI-powered X-ray interpretation tool. In mere seconds, it highlights the same diagnoses he meticulously verbalized, stripping away the illusion that his decades of training offered any insulation from the future.
“This is scary,” he says, almost laughing—but it’s the nervous laugh of someone standing at the edge of a professional cliff. “I developed this skill over 20 years... and here comes AI and they pick it up in a second.”
AI: The Ultimate Overachiever?
Artificial Intelligence was once thought to be a helper, an assistant in the workflow. But what happens when the assistant becomes the expert—and faster, cheaper, and potentially even more accurate?
For years, the narrative around AI replacing jobs focused on the so-called "simple" ones—data entry, customer service, even some writing roles. The underlying belief was that creative, skilled, and interpretive professions would be safe. Medicine, especially, was held up as one of the final frontiers—requiring years of education, precise judgment, and above all, human empathy.
But AI is now peering over that fence. It’s not just chatbots and copywriters who are feeling the heat. Coders were recently dealt a blow when Mark Zuckerberg announced Meta’s ambition to have 50% of its programming done by AI agents. And now, doctors are confronting the same cold efficiency.
Medicine’s Murky Future: Human Insight vs Machine Speed
What’s most unsettling for professionals like Dr. Fawzi is not just the competence of AI—it’s the implications for their very identity. His job wasn’t just about knowing what pneumonia looks like; it was about the years it took to know it deeply, intuitively, instantly. That journey, it seems, can now be leapfrogged by a machine in milliseconds.
The regulatory frameworks in healthcare, thankfully for many, still uphold human oversight. Licensing boards, patient consent, and ethical considerations ensure that AI isn’t yet flying solo in most hospitals. And while AI can analyze, it can’t comfort, contextualize, or respond to the emotional weight of a diagnosis.
One commenter on Dr. Fawzi’s post echoed this hope: “Just because AI can do that doesn’t mean it’s 100% correct all the time.” Another added, “I don’t care if it costs extra. I’d much rather have a doctor and AI working in tandem than AI diagnosing me alone.”
The New Co-Worker or the Future Boss?
So is AI here to replace doctors, or redefine them? That’s the existential question haunting not just healthcare, but every skilled field that once believed itself too complex to automate.
For now, experts like Dr. Fawzi might not be handing in their stethoscopes, but the discomfort is real. AI may be a boon for efficiency and accuracy, but for the workers whose sense of purpose and livelihood depend on tasks now rendered algorithmic, the boom feels like a betrayal.
In Dr. Fawzi’s words, half-joking and half-dreadful: “So I’m going to be applying to McDonald’s soon. I hope they have some openings.”
Whether that becomes a reality or remains a grim jest depends on how society chooses to integrate intelligence—both artificial and human—in the years to come.
