AI’s next bottleneck may not be chips or data centers, but the physical limits of Earth itself. With more than $700B in AI capex commitments in 2026, today’s infrastructure race risks creating massive amounts of underutilized capacity. The longer-term opportunity may lie beyond Earth: orbital power, cooling, manufacturing, and eventually, orbital data centers. The companies thinking in terms of space infrastructure, not just terrestrial compute, may ultimately define the next era of AI.
AI adoption in healthcare is accelerating rapidly, but trust is lagging behind. As organizations scale AI across clinical and administrative workflows, the next challenge is proving that these tools are safe, transparent, clinically valid, and capable of delivering measurable outcomes.
Medical debt affects tens of millions of U.S. adults and has emerged as a recognized social determinant of cardiovascular health. This narrative evidence synthesis reviews the current peer-reviewed and gray literature linking medical debt and related financial hardship to cardiovascular disease (CVD) prevalence, incidence, and outcomes. Across nationally representative surveys, county-level administrative data, and prospective cohorts, financial hardship from medical bills is consistently associated with a higher prevalence of cardiovascular risk factors, worse self-reported cardiovascular health, cost-related medication nonadherence, and elevated all-cause and cardiovascular mortality. Proposed mechanisms include chronic psychosocial stress and allostatic load (sustained hypothalamic-pituitary-adrenal axis activation and systemic inflammation), as well as behavioral pathways such as delayed care-seeking, medication rationing, and foregone preventive services. The burden of medical debt and its cardiovascular consequences falls disproportionately on Black and Hispanic adults, low-income households, the uninsured and underinsured, and residents of non-Medicaid-expansion states, reinforcing existing cardiovascular health disparities. Policy interventions that reduce uninsurance and out-of-pocket exposure, most notably Medicaid expansion, are associated with reduced medical debt, reduced catastrophic health expenditure, and improved cardiovascular outcomes at the population level.
