We work with whoever is elected. Some will bring a more generous, open view of the world than others.

Personally, I'd like to see more of our leaders take a technocratic approach to solving our biggest problems.

When you program, you want to think you're writing the best possible program for the... for the task you're trying to solve.

No one person controls Microsoft. The board and the shareholders decide whether they want to have me as CEO.

The next time someone tells you we can trim the budget by cutting aid, I hope you will ask whether it will come at the cost of more people dying.

If you really could take the CO2, when you burn hydrocarbons - coal, for example - if you could really capture the carbon and sequester it - they call it CCS - if the extra capital cost, energy cost, and storage costs over time didn't make it super expensive, then that's another path that you could go down.

On the supply side, for innovation, you'd say, go look at those R&D budgets, and they haven't moved in the last 20 years. In the case of the US - which is the majority of R&D funding across every category you can name: health, energy, whatever - it's been about $5 billion a year from the Department of Energy.
