Your genome isn't really secret.

Healthcare is becoming part of information technology.

Government is really successful when it's willing to make big, bold objectives, like, 'We're going to get to the moon.' But without leaders with big ideas, we get stuck.

I can make it very clear: I get paid if we make good investments. And if we don't, I don't get paid. I have no incentive to sell our companies to Google; the entrepreneurs get to decide that. We are minority shareholders.

If you want to invest in early-stage technologies, putting a timeframe on it does behold you to Silicon Valley economics. You've got a certain time period where you have to make the money. And you have to invest that money whether you find good companies or not.

If you're a technology investor, and you decide that you're also going to be a healthcare investor or a green-tech investor, that doesn't usually work out that well. There are reasons why people make their careers studying these things and becoming experts.

If I were to leave and raise a venture fund, I would have to find 10 or 100 LPs. They would all give me a bunch of money, and I would take a percentage of that to pay myself. They would expect me to invest that over the next three years, and they want that money back in seven or eight years.

I'm interested in the ideas that sound a little crazy, such as radical life extension, curing cancer, being able to create a simulation of the human brain and map every neuron.

Not many venture firms have people whose job is to read academic research - on startups, ventures, and entrepreneurs - and gather knowledge from that.

As life expectancy extends beyond 80 years in some parts of the world, more people are struggling with brain diseases. For older people, Alzheimer's, Parkinson's, and other conditions become a major impediment to quality of life.
