最深刻的技术是那些消失的技术。它们将自己编织进日常生活的结构中，直到与生活无法区分。

We must balance economic growth with environmental stewardship.

Don't wait until everything is just right. It will never be perfect. There will always be challenges, obstacles and less than perfect conditions. So what. Get started now. With each step you take, you will grow stronger and stronger, more and more skilled, more and more self-confident and more and more successful.

求知若渴，大智若愚。这是我一直想做到的。眼下正值诸位大学毕业、开始新生活之际，我同样愿大家：Stay Hungry. Stay Foolish. 好学若饥、谦卑若愚。
