我突然想到一个事实：人工合成牛胰岛素丶青蒿素丶哥德巴赫猜想丶完备的工业门类和体系丶完整的农田水利设施，全民扫盲与高中普及教育，全民医疗与医疗卫生机构建设普及，不都是在前三十年完成的。比一比后四十年虽说物质丰富了，但有很多方面没有进步甚至是退步不少，且原创性的东西太少简直不值一提。
I suddenly think of the fact that synthetic insulin and artemisinin-based insulin are the perfect industrial sectors and systems of the Godebach, that universal literacy and high school education, and universal access to health care and health care have not all been completed in the first 30 years. More than in the last 40 years, there has been no progress, or even setbacks, in many respects, and that the originals are too few to mention.
