First part in the series - healthcare companies I think someone should build 1. DME recycling marketplace: A third-party marketplace that re-certifies used durable medical equipment (CPAPs, power wheelchairs, unopened diabetes supplies) so it can be resold legit instead of tossed 2. World's Fair for healthcare: A new World's Fair where people can actually see and touch cutting-edge healthcare tech, like a live Neuralink demo or a Wandercraft exoskeleton. The point is to make people amazed by healthcare again, the way the old fairs did for consumer tech. 3. Instinct for healthcare workers: A personal AI agent built for healthcare employees, with its own login on the org's network, a BAA-covered cloud model, and role-based permissions instead of impersonating you with cached passwords. People are going to use these tools at work no matter what, so someone should build the compliant version.
