Personally feel:
1: Due to the development of computers and networks, the development of embedded systems is unlimited.
2: Because the embedded system is relatively closely intellectual, it is difficult to form a large company monopoly, and the big company has to rely on many small companies. In this field, each company has an opportunity to have a profit.
BTW: There is a good e-book on the embedded system, and the head is simple. Since a lot is related to hardware, it is hard to understand, it seems to look back.
