Well, I think that if I define my field as infectious disease, I’d say community-based care for chronic infectious disease, or new therapeutics are in the pipeline. If I define my field as public health, I would say strengthening health systems, right? But if I define my field more broadly, as development and social progress, I would say the biggest developments are going to be bringing together a growing movement around social justice, and linking that to the growing movement for environmental justice. I think once these things come together, that we’re going to see a lot of social progress in the planet. So yeah, any of those. That’s all optimism for you.
