There is almost no underlying computer technology in China.

As far as I know, the underlying technology is still relatively comprehensive, but chips, operating systems, compilers and so on. Those who reach the top level in the world are really a little worse.

For example, CPU design has Shenwei and Godson. The operating system has wings. In fact, there are quite a few compilers, such as Easy Language, gcc porting to Loongson.

In fact, there are quite a few people who are engaged in the basic technical work of computers. The point is that these underlying technologies don't make money.

I chose computer hardware as my major at that time. At that time, the experimental board was needed in the course of computer composition principle. The experimental board was expensive and difficult to maintain, but it was still very advanced at that time, and there were even some export orders. There are also many inconveniences for students to use. Several other students and I just want to help the teacher make a virtual experimental version, so that students can learn related courses without those experimental boards. Doing a good preview can improve the efficiency of using the experimental board. Although we insisted repeatedly, we finally made a simple virtual experiment board system. But my teacher told us seriously that he had worked in this field all his life and felt that there was no hope in this field. I hope we can make software.

In fact, there are many similar phenomena. For example, many scientists who engaged in two bombs and one satellite in those years were top candidates in the college entrance examination. They stayed in the base for more than ten years, but the treatment after decades may not be ideal. If nothing else, the recruitment of Tianyan project scientists only earns hundreds of thousands a year, while experts at the same level in Ali can earn millions a year. This gap makes many top talents unwilling to do these things.

However, some successful experiences abroad are difficult to replicate at home. For example, many people know that linux is the work of Linus, but in fact, FSF (Free Software Foundation) has played a decisive role in the development of Linux.

However, I think people who want to do things should not care about these economic problems, as long as they are hungry. I hope one day I can see that the underlying computer technology has your share.
