Certainly there's a phenomenon around open source. You know free software will be a vibrant area. There will be a lot of neat things that get done there.

Since when has the world of computer software design been about what people want? This is a simple question of evolution. The day is quickly coming when every knee will bow down to a silicon fist, and you will all beg your binary gods for mercy.

Depending on how quickly you get ocean rise, you have people who live in river deltas [at risk]. Bangladesh is largely a river delta, and the rising sea level means that when storms come in, the human sanitation is backing up, the ability to farm, it's destructive-type situations like you saw in New Orleans with Katrina. You're increasing the frequency of that stuff in low-lying areas fairly dramatically.

There are more people dying of malaria than any specific cancer.

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.

I considered law and math. My Dad was a lawyer. I think though I would have ended up in physics if I didn't end up in computer science.
