This week at OH @ @usv: The case for remutualizing essential services, AI agents putting patients in control of their health data, decentralized AI breaking big tech’s grip, healthier digital habits, and the sweet spot for micropayments. 🧵

Your Health, Your Data: HIPAA grants patients the right to access and transfer their health data, but this right is often underutilized. AI agents could change that by streamlining the collection and organization of medical records, making data portability a practical reality. Acting as advocates, these agents would empower patients to take rightful ownership of their health information, enabling better decisions and shifting power in healthcare toward individuals.

Healthier Digital Habits with AI: We’ve been talking a lot recently about tools for digital detox. One counterintuitive thread is that AI could actually become an ally. It can transform screens into tools for intentional productivity rather than distraction, helping us find what we need faster while nudging us away from unproductive habits. This is possible because It has a different business model and different incentives than the ad based web we know today. Of course, that will only stay true if....

Decentralized AI, Decentralized Power: The recent decentralized training of a 10-billion-parameter model demonstrates a scalable, collaborative approach to AI development. By pooling resources globally, this method enables diverse stakeholders to participate while reducing data privacy risks. Decentralization is critical to breaking the dominance of a few large companies, fostering a more competitive and equitable AI market.

The Sweet Spot for Micropayments:  Micropayments excel when costs and value are predictable—like paying for storage, computation, or inference near marginal energy costs. But they falter in uncertain scenarios, like pricing an answer without clear quality metrics. Bundling solutions often bridge the gap, delivering value on average. The challenge? Pricing for personalization remains an open problem, demanding innovative intermediaries or future zero-knowledge breakthroughs.

The Need for Remutualization: Co-op models once anchored essential services—like health insurance and utilities—firmly in local hands. Today, crypto protocols can revive that trust, embedding transparent governance and shared incentives directly in code. By removing gatekeepers and intermediaries, communities can shape and refine their own rules over time. The result is a radical reimagining that ensures equity, accountability, and resilience define how we deliver these critical systems.
