Design is a funny word. Some people think design means how it looks. But of course, if you dig deeper, it's really how it works. The design of the Mac wasn't what it looked like, although that was part of it. Primarily, it was how it worked.

You see, researchers have coined this term "color blindness" to describe a learned behavior where we pretend that we don't notice race. If you happen to be surrounded by a bunch of people who look like you, that's purely accidental. Now, color blindness, in my view, doesn't mean that there's no racial discrimination, and there's fairness. It doesn't mean that at all. It doesn't ensure it. In my view, color blindness is very dangerous because it means we're ignoring the problem.

What I want to do this morning is share with you a couple of stories and talk about a different Africa. Already this morning there were some allusions to the Africa that you hear about all the time: the Africa of HIV/AIDS, the Africa of malaria, the Africa of poverty, the Africa of conflict, and the Africa of disasters. While it is true that those things are going on, there's an Africa that you don't hear about very much. And sometimes I'm puzzled, and I ask myself why. This is the Africa that is changing, that Chris alluded to. This is the Africa of opportunity. This is the Africa where people want to take charge of their own futures and their own destinies.

The strategy we've adopted precludes our following standard diversification dogma. Many pundits would therefore say the strategy must be riskier than that employed by more conventional investors. We disagree. We believe that a policy of portfolio concentration may well decrease risk if it raises, as it should, both the intensity with which an investor thinks about a business and the comfort-level he must feel with its economic characteristics before buying into it.

Oh, hands down, I’m most proud of the people that I’ve trained and the people that have come from my work — I mean from my lab. I think that when I look at these younger people who are now working in their own right, running research laboratories, doing great work, teaching their students, making new discoveries, that’s what I’m proudest of. That legacy of science that stemmed from — originally — just me opening up my shop at Yale University back in 1994.
