Fortunately, what motivates most significant advances in knowledge is not profit, but the pursuit of knowledge itself. This has been true of all of the transformative discoveries and innovations – DNA, transistors, lasers, the Internet, and so on.
所幸激励那些最重大知识进步的并不是利润，而对知识的追求本身。在革命性的发现和创新上——比如DNA、晶体管、激光、因特网等等——都是如此。
