I get more spam than anyone I know.

The malaria parasite has been killing children and sapping the strength of whole populations for tens of thousands of years. It is impossible to calculate the harm malaria has done to the world.

The trouble with energy farming is that the energy isn't always where you want to use it, and it isn't always when you want to use it.

The difference between a stranger sending you a message that you might be interested in at a very low volume level, no repetition, just sending it to very few people, and that being done as spam - those things get close enough that you want to be careful never to filter out something that's legitimate.

There's a true schizophrenia where if you say to voters, you know, do you think the federal government spends too much money and they should spend less, they say yeah, absolutely. Then you name specific things, like Pell grants for students and they say, no, not that. How 'bout NIH, medical research funding? Nah, you really shouldn't cut that. And pretty soon you've proved that what the American public is against is arithmetic.

I think Ebola is a great example of where the world really needs to come together. The three countries where this outbreak took place have had a lot of civil war, very weak health systems.

I think it is quite impressive what's being pulled together, and I think we will be able to get this under control.
