主题：从四代看我们的工业的赶超道路 -- 桃子甜
看不同领域。而且这个差距在急剧缩小。
更多地取决于自己
创新，我们来制造就行了，希望以后美国全是搞理科的，工科我们包圆就行了，本身这几代中国人的创新意识就差点，赶超不着急，也不好赶。
阅读方便些。
军事工业不完全等同于科技经济水平，
但是可以作为一个大概衡量的标尺。
当年苏联的工业技术，整体实力，也是数一数二的。
我想我们现在的四代，也有一些技术验证的成分吧。
考虑美帝在冷战结束后，放慢了Ｆ２２的发展，２０年的差距还是有的。
里面有一句和你的表述一致
I was one of those elementary school students who benefited from math and science education after Sputnik.
When I saw this graphic in the magazine I wanted to put it on billboards on the busiest freeways in every city in America - especially in those cities where those members of congress live. We spend more on finding new ways to kill people that all other research combined.
It's nice that NIH has research funding, but there is now less venture capital available for development of that research into useful products. I was one of those elementary school students who benefited from math and science education after Sputnik. It's sad to see NASA so reduced in scope and vision compared to military.
This graphic portrays the future of a doomed society.
源源不断的新老中正在排队进入美国。反正我的同学已经大部分在为美国的科研机器服务了。不过这些年选择回来的也确实越来越多了。
美国问题一堆，国内只怕更多不少，不说别的，那个20年不吃不喝工资才能买的起的房价就让多少人选择离开。
对不起扫大家兴了，不过我希望有更长远更坚实的进步
从这个，就可以大体分析得出四代性能指标的取向，当然还得考虑tg在各相关技术上的储备，做出取舍！
国家战略决定空军方向，空军方向决定装备状态！
军事也好科技也好说白是国家政治斗争的一种延续。最激烈的政治斗争就是军事。所以任何最优秀的科技都会首先运用到军事领域。而军事领域也是最极端最迫切需要最新科技的地方。
在高兴，一片叫好的同时，也需要兄台这样的冷水泼一泼。只要出发点都是为了中华民族的长远复兴。
毕竟我们的路还很长，挑战，问题还很多。在全球博弈中，一招不慎，还会有重大损失的。
我们的工作将写在人类的历史上，它将表明占人类总数四分之一的中国人从此站立起来了。
我们将不但有一个强大的陆军，而且有一个强大的空军和一个强大的海军。
让那些内外反动派在我们面前发抖吧，让他们去说我们这也不行那也不行吧，中国人民的不屈不挠的努力，必将稳步地达到自己的目的。
一九四九年九月二十一日，毛泽东主席在中国人民政治协商会议第一届全体会议上致开幕词

There have also been persistent rumors of other Chinese fighter concepts, still on the drawing boards: aircraft reportedly intended to bridge the remaining gap between China and the most advanced of American jet fighters. Rumors of a theoretical, low-observable or 'stealth' fighters abound, reportedly based on an evolved, twin-engined version of the J-10. These concepts, however, remain little more than paper 'wish lists' circulated in the realm of fantasy. For a nation that is still dependent on Russian technology to supply engines and electronics for its most basic of fighter needs, the possibility of developing a stealth aircraft in the class of the F-22, or even the F-117, is remote. Even the Soviet Union, at its height, struggled to keep pace with American technical achievements in this arena. Even the Europeans, who have a broader technology base from which to launch their efforts, have lacked the financial wherewithal to develop a true 'stealth' fighter in the same class as the F-22 or F-35.

实际上过去几十年美国科技的进步基本上都是靠军事技术上投入得来的。宇航技术也是军事技术的一方面。
