Here are the problems I find most important and motivating:
Human capability. What would the world be like if we were wiser, kinder, and more capable? What makes people grow and perform at the highest level? How do we empower and inspire people to face the important problems in their lives, communities, and societies?
Process and infrastructure. What tools can we create to make humankind more capable and creative? What systems will future generations wish we had started building now?
Climate change. What are the most effective ways to manage and mitigate the effects of climate change on human civilization? (Answer: work at Evergrow!)
