I imagine each partner will have different answers. One thing I say is that we should be willing to fund anything that could be a $10B company, and that is such a difficult restriction we shouldn't have any other restriction.

Personally, I am very interested in nuclear energy and solar (I think energy is the highest-impact single thing to fix--it's remarkable how many other problems reduce to the energy problem), biotech, AI, education, healthcare, and online communities.

Interestingly, those first three categories are also where I think the biggest dangers to humanity are. High-risk high-reward, I guess.

What do you think about wind energy? A leading wind energy company here in India just had a $160M IPO here and it was oversubscribed. Wind is also growing faster than solar in large parts of the world.
