阎友们，
大家好。
对于波音飞机接二连三的事故的根本原因，本期与大家分享老阎观点。欢迎大家在评论区讨论提出你的看法。
谢谢大家。

以下观点源于阎文《圣母教堂大火-天灾与人祸》
人类的文明史表明：创新历来跟着制造业走，这与信仰、种族无关。当年阿拉伯世界的建筑业领先人类。同样是一神教，制造业从英国转到德国，科学技术创新也同时到了德国；随着制造业从德国转到美国，科学技术创新也到了美国。波音出事不是偶然的，在美国制造业外移之前，波音飞机的零部件90%以上由美国制造，今天，90%由外国制造。一个只造10%零部件的公司，不论软件是否是外包给印度，公司把精力放在如何快速赚到现金上，研发就只能跟随零部件制造者离开美国了，因为美国的工程师无法闭门造车。
人类科学史表明：技术创新是跟着制造业市场走的，没有了制造业，就无法知道技术关卡在哪里。知道后，便可群策群力突破它而搞出创新产品。
Friends of Yan,
Hello everyone.
Regarding the series of accidents involving Boeing aircraft, we would like to share Lao Yan’s views of root cause. To join in the conversation, please feel free to express your thoughts in the comments section.
Thank you all.

Summary of Runtao’s conclusion
The history of human civilization demonstrates that innovation has always followed production, regardless of race or religion. Islamic architecture from Arab and Muslim-majority nations has been at the forefront of humankind since the 7th century, and its impact has grown all over the world. Later, Germany outperformed Britain in manufacturing, so did German science and technology innovation outpace Britain. The same thing happened when the US manufacturing surpassed German production while the US was leading the world in invention.
What happened to Boeing was not an accident. Prior to the relocation of American manufacturing abroad, over 90% of Boeing’s aircraft components were produced domestically. Currently, 90% are produced abroad. Because American engineers are unable to develop behind closed doors, a firm that produces only 10% of its components must outsource its R&D to foreign manufacturers, which result the corporation to prioritize short-term cash returns over long-term R&D investments.
The history of human science shows that technical innovation is driven by the manufacturing market. Without manufacturing, it would be impossible to know where the technological barriers are. Once you know it, you can work together to break through it and come up with innovative products.
