AI models will quickly automate the majority of expert work, but they will struggle with the final, most complex 25%. For a long time, human expertise will be essential for this 'last mile,' making it the ultimate bottleneck and source of economic value.

As AI handles complex diagnoses and treatment data, the doctor's primary role will shift to the 'biopsychosocial' aspects of care—navigating family dynamics, patient psychology, and social support for life-and-death decisions that AI cannot replicate.

Instead of choosing a career based on its perceived "safety" from AI, individuals should pursue their passions to quickly become domain experts. AI tools augment this expertise, increasing the value of experienced professionals who can handle complex, nuanced situations that AI cannot.

As AI tools become operable via plain English, the key skill shifts from technical implementation to effective management. People managers excel at providing context, defining roles, giving feedback, and reporting on performance—all crucial for orchestrating a "team" of AI agents. Their skills will become more valuable than pure AI expertise.

The next evolution in personalized medicine will be interoperability between personal and clinical AIs. A patient's AI, rich with daily context, will interface with their doctor's AI, trained on clinical data, to create a shared understanding before the human consultation begins.

Despite hype in areas like self-driving cars and medical diagnosis, AI has not replaced expert human judgment. Its most successful application is as a powerful assistant that augments human experts, who still make the final, critical decisions. This is a key distinction for scoping AI products.

If AI were perfect, it would simply replace tasks. Because it is imperfect and requires nuanced interaction, it creates demand for skilled professionals who can prompt, verify, and creatively apply it. This turns AI's limitations into a tool that requires and rewards human proficiency.

An effective AI strategy in healthcare is not limited to consumer-facing assistants. A critical focus is building tools to augment the clinicians themselves. An AI 'assistant' for doctors to surface information and guide decisions scales expertise and improves care quality from the inside out.

The value of a personal AI coach isn't just tracking workouts, but aggregating and interpreting disparate data types—from medical imaging and lab results to wearable data and nutrition plans—that human experts often struggle to connect.
