Advanced health tech faces a fundamental problem: a lack of baseline data for what constitutes "optimal" health versus merely "not diseased." We can identify deficiencies but lack robust, ethnically diverse databases defining what "great" health looks like, creating a "North Star" problem for personalization algorithms.

Many genetic tests for personalized nutrition are validated on narrow populations, like European Caucasians. These genetic markers often have zero predictive power when applied to other ethnic groups, such as those of West African descent, making their recommendations highly unreliable for a diverse user base.
Many pharma companies chase advanced AI without solving the foundational challenge of data integration. With only 10% of firms having unified data, true personalization is impossible until a central data platform is established to break down the typical 100+ data silos.
While wearables generate vast amounts of health data, the medical system lacks the evidence to interpret these signals accurately for healthy individuals. This creates a risk of false positives ('incidentalomas'), causing unnecessary anxiety and hindering adoption of proactive health tech.
The goal of advanced in-home health tech is not just to track vitals but to use AI to analyze subtle changes, like gait. By comparing data to population norms and personal baselines, these systems can predict issues and enable early, less invasive interventions before a crisis occurs.
The current trend of building huge, generalist AI systems is fundamentally mismatched for specialized applications like mental health. A more tailored, participatory design process is needed instead of assuming the default chatbot interface is the correct answer.
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.
The progress of AI in predicting cancer treatment is stalled not by algorithms, but by the data used to train them. Relying solely on static genetic data is insufficient. The critical missing piece is functional, contextual data showing how patient cells actually respond to drugs.
The bottleneck for AI in drug development isn't the sophistication of the models but the absence of large-scale, high-quality biological data sets. Without comprehensive data on how drugs interact within complex human systems, even the best AI models cannot make accurate predictions.
Leading longevity research relies on datasets like the UK Biobank, which predominantly features wealthy, Western individuals. This creates a critical validation gap, meaning AI-driven biomarkers may be inaccurate or ineffective for entire populations, such as South Asians, hindering equitable healthcare advances.
A major frustration in genetics is finding 'variants of unknown significance' (VUS)—genetic anomalies with no known effect. AI models promise to simulate the impact of these unique variants on cellular function, moving medicine from reactive diagnostics to truly personalized, predictive health.
