每年的TED(TED為：科技technology、娛樂entertainment、設(shè)計design的縮寫)大會都會聚集全球卓越的思想家，就科學(xué)、藝術(shù)、政治、全球性問題、建筑、音樂等各個領(lǐng)域的問題進行交流。今年比爾·蓋茨也受到了大會的邀請，在"重啟(Rebooting)"環(huán)節(jié)進行了精彩的演講。有意思的是，蓋茨在大會會場上散播了一些蚊子，他稱，"沒有理由只是讓窮人體驗被蚊子攻擊的滋味"。?

Bill Gates hopes to solve some of the world's biggest problems using a new kind of philanthropy. In a passionate and, yes, funny 18 minutes, he asks us to consider two big questions and how we might answer them.

Bill Gates is founder and former CEO of Microsoft. A geek icon, tech visionary and business trailblazer, Gates' leadership -- fueled by his long-held dream that millions might realize their potential through great software -- made Microsoft a personal computing powerhouse and a trendsetter in the Internet dawn. Whether you're a suit, chef, quant, artist, media maven, nurse or gamer, you've probably used a Microsoft product today.

In summer of 2008, Gates left his day-to-day role with Microsoft to focus on philanthropy. Holding that all lives have equal value (no matter where they're being lived), the Bill and Melinda Gates Foundation has now donated staggering sums to HIV/AIDS programs, libraries, agriculture research and disaster relief -- and offered vital guidance and creative funding to programs in global health and education. Gates believes his tech-centric strategy for giving will prove the killer app of planet Earth's next big upgrade.

"When Gates looks at the world, a world in which millions of preventable deaths occur each year, he sees an irrational, inefficient, broken system, an application that needs to be debugged. It shocks him -- his word -- that people don't see this, the same way it shocked him that nobody but he and [Paul] Allen saw the microchip for what it was."
