For about 10 years, I have been buying cut forests in Massachusetts and working to plant and restore native trees. 🌲 They slowly grow into a canopy and mitigate the invasive species. Animals return. All together, I estimate we're sinking about 1000 tones of CO2 per year now.

How will humans adapt to AI?
If intelligence and labor become commodities, what will be the new human value system?
What will humans learn when they will never be as smart as their phone? What will humans do in an age of abundance?

Humans seem to be so divided in how they use AI. For some, it is like a learning and productivity companion leading to huge economic gains. For others it replaces thinking and learning, causing a downward spiral of ignorance and dependence. Is this a new skill required for human thriving?

The difference between what is possible in a lab and what is deployed by industry seems to be widening. Industry is slow to adopt AI, careful and conservative, and the timelines generally end up being longer than what the smartest people expect.

What are the fundamental sources of value in a world of ASI and robots of all types? I think primary/proprietary data and network effects will still lead to defensible margins. What else?

Today China has huge advantages in manufacturing. Will it will dominate the embodied AI trend? Will it manufacture and iterate on robots with a sustainable advantage? Or will manufacturing evolve so only supply chains, power, and physical space will matter?

In software and AI, there is a lot of talk of "digital twins".
These are simulations that allow AIs to learn before acting in real life. Think of the software digital twin as an imagination. It's a world where AI can learn and consider lots of alternate possibilities.

There is not enough electricity production in the US. But the solution is not to shut down data centers; instead, charge progressive rates: cheap for households with small demand, and more if you consume a lot. Solve the problem with better incentives.
