Microsoft has recently revealed a new AI system they say is 4 times more effective than doctors in diagnosing complex illnesses.

Does this mean AI will soon take over from doctors?

Bill Gates appears to believe so. During a recent episode of The Tonight Show, he stated that AI could eliminate the need for human physicians “for most things” within ten years, bringing about an era of low-cost, robot-led healthcare — something like Disney’s Big Hero 6 character Baymax.

But Gates is mistaken.

AI will certainly transform medicine significantly as systems like Microsoft’s and others are adopted into medical practice. However, it won’t replace the majority of what doctors do — at least not in the foreseeable future. Rather than replacing doctors, AI is becoming their most powerful assistant, helping them work more efficiently and improve patient care.

What AI Can Do As Well (Or Better) Than Doctors Today

The case for AI replacing doctors largely rests on its ability to perform key medical tasks. It's true that AI excels at analyzing digital data.

Take radiology, where much of a physician’s time is spent interpreting X-rays, CT scans, MRIs, and other imaging studies. A 2019 review published in Lancet Digital Health showed that AI can match or surpass human radiologists in image classification.

Dermatology is another field where AI is making strides. Skin conditions can be photographed and analyzed by AI models that now perform as well as, or better than, board-certified dermatologists in identifying skin cancer.

Pathology is similar. A 2024 meta-analysis in Nature found that AI achieved 96% sensitivity and 93% specificity across 48 studies in clinical pathology diagnosis.

When data is clean and digitized, AI is already outperforming doctors — or will soon. Where it isn't yet superior, it likely will be shortly.

Why AI In Healthcare Won’t Replace Most Doctors Anytime Soon

Even in fields such as radiology, dermatology, and pathology, AI won’t fully take over.

At the Mayo Clinic, AI is being used to enhance radiologists' capabilities rather than replace them. Radiologists don’t just interpret images; they also coordinate with other specialists, communicate with patients, and perform procedures like biopsies or interventions for stroke and infections.

Similarly, dermatologists conduct biopsies and treat patients directly in clinics. Pathologists carry out autopsies and offer expert opinions on difficult cases.

These hands-on responsibilities can’t be handed off to AI.

What about surgery? Research shows AI can aid in precision, but it cannot autonomously perform procedures. Surgery remains one area where human skill and experience are irreplaceable.

Another obstacle is public perception. A 2023 survey found that 64% of patients would trust an AI diagnosis over a human one — but trust declines when dealing with serious or complex health issues.

As evidence accumulates showing AI’s safety and accuracy, attitudes may shift. But one essential element of healthcare — empathy — remains uniquely human. A 2011 study in Academic Medicine found that patients of more empathetic physicians had better diabetes control, proving that emotional connection impacts real-world health outcomes.

AI In Healthcare Will Be The Doctor’s Smart Copilot

Rather than replacing doctors, AI is becoming their smart copilot. As organizations integrate AI tools more deeply and clinicians adopt them widely, these systems will help reduce routine burdens and allow doctors to focus on critical thinking, nuanced decisions, and meaningful patient interactions.

One current example is how doctors use AI to assist in generating differential diagnoses. For rare pediatric diseases, AI helps identify combinations of symptoms that point to a specific condition.

Platforms like OpenEvidence, available only to licensed physicians with a National Physician Identifier, help clinicians quickly access up-to-date research and evidence-based answers.

A promising application of AI is automating clinical documentation. Doctors today spend nearly half their time on paperwork. Voice-driven AI assistants are beginning to ease this burden, especially in outpatient settings.

All of these tools are designed to support doctors, not replace them.

What Will Determine AI in Healthcare’s Future Role?

AI capabilities are growing fast, but adoption varies — especially in clinical environments where workflows aren’t yet optimized.

For instance, ambient AI for note-taking is helpful for some doctors, while others abandon it due to poor integration with their specialty or excessive editing needs. Some find existing methods like dictation still work best.

In some areas, AI has underperformed expectations. For example, sepsis detection algorithms in hospitals are often overridden by physicians, highlighting the continued importance of human expertise in dynamic clinical situations.

Regulation is also evolving. Initiatives like the FDA’s Digital Health Precertification Program and the European Union’s AI Act aim to clarify oversight. But major concerns remain around privacy, bias, and legal accountability. If an AI system misses a cancer diagnosis, who is liable? These uncertainties make many healthcare systems cautious about full-scale AI deployment.

How Can AI In Healthcare Be Optimized?

Most importantly, AI must address real clinical challenges — improving decision-making and efficiency.

An excellent example comes from emergency medicine: the AI tool “Queen of Hearts” helps detect subtle EKG changes that suggest a heart attack. The software has received FDA Breakthrough Device designation and may be approved for use soon.

Another challenge is the rapid pace of AI development. Medical education must keep up. Leading schools like Stanford and Harvard have begun incorporating AI into their curricula, but most practicing clinicians lack training on how to use these tools effectively.

Ultimately, AI may relieve doctors of cognitive and administrative tasks, allowing them to focus on what humans do best: connect, empathize, and perform hands-on procedures. Physicians will also need training to oversee and collaborate with AI systems.

So, Bill Gates, we’re sorry to say — the future of AI in healthcare won’t look like Baymax. Instead, it will involve smarter, more efficient care delivered by human doctors using intelligent tools.
