I write The Roots of Progress, a blog about the history of technology and the philosophy of progress. Some of my top posts:
I am also the creator of Progress Studies for Young Scholars, an online learning program for high schoolers; and a part-time adviser and technical consultant to Our World in Data, an Oxford-based non-profit for research and data on global development.
My work is funded by grants from Emergent Ventures, Open Philanthropy, the Long-Term Future Fund, and Jaan Tallinn (via the Survival and Flourishing Fund).
Previously, I spent 18 years as a software engineer, engineering manager, and startup founder.
Ask me anything!
UPDATE: I'm pausing for now but will come back and I will try to get to everyone, thanks for all the questions!
I think basically you have to look at where an innovation sits in the tech tree.
Energy technologies tend to be fundamental enablers of other sectors. J. Storrs Hall makes a good case for the need to increase per-capita energy usage, which he calls the Henry Adams Curve: https://rootsofprogress.org/where-is-my-flying-car
But also, a fundamentally new way to do manufacturing, transportation, communication, or information processing would enable a lot of downstream progress.
