Stardust, I agree with a lot of what you wrote, except for zero developed part. There are now exceptions. One of them is XPENG.
https://www.crunchbase.com/organization/xiaopeng-motors - "Xpeng is equipped with experts from top companies in the field such as Tesla, Mercedes-Benz, Porsche, Ford, Mazda, GAC Motor, Alibaba Group, Tencent, Huawei, P&G and Mi, and more."
Not surprising is that they have an office in Silicon Valley, CA, USA. If you look at how American tech companies have dominated, they were always able to lure and hire the smartest people from anywhere. XPENG is doing the same.
I started following the company about 9 months ago. Li, Nio and Xpeng are the big 3 in EV in China. Nio gets a lot of publicity but I think it's a lot of hype. Li is only doing hybrids currently which makes sense with the very limited amount of charging stations. Xpeng went the low price route originally, but is upscaling and has the superior tech. Their autonomous software is rated as the best currently available. I own 1,000 shares. Almost also bought Li but decided I didn't want to risk too much on Chinese stocks.
We could start with Gottlieb Daimler whos invention was the first car in the world born in Schorndorf, Germany and give his first car the name Mercedes because it was the name of his daughter til today and you would not find any chinese invention in the automotive industry from Germany or worldwide. In this chains you could mention Henry Ford he invented the mass productions of cars. Do you ever been in Stuttgart (Mercedes, Porsche) and all the surrounding towns or region with all these automotive suppliers, developpers? I guess not. And why IBM gave up their big branches there in Stuttgart?! I am talking also about software developper and hardware in that region! If you know a little bit about the automotive industry then you would know, it would not enough space to mention all that companies from their and about developping automotuve inclusive all the machine builders for the car production. And now guess who build up the automotive productions in China or ask anybody in Germany if there is anything invented from China! Ok enough said.
