When I say the EDA niche, I was referring to the EDA programming sector within China who work for China based EDA companies. They are basically competing with a global triopoly (Cadence, Synopsys, Mentor Graphics) who each have thousands of programmers while the entire EDA software industry in China numbers around 300 technical staff. The situation with EDA in China is similar to the situation in the aerospace sector where there are only 11000 employees at COMAC of which a few thousand are researchers while Boeing and Airbus have over 130000+ employees each with tens of thousands of researchers, not assembly line or maintenance workers. Alot of China pundits often claim China will quickly catch up in this or that technology sector just by brute force investment because they look at how big China is as a nation while forgetting that in certain specific sectors of China, there remain alot of chokehold bottlenecks where China is still at the infancy / juvenile stage of those industries.
This is a major reason why China has struggled mightily in certain industries despite pouring many billions into certain areas because they haven't reached critical mass in those areas. China just so happened to reach critical mass in a tonne of industries during 2005-2020 which coincides perfectly from when Jiang Zemin/Zhu Rongji tenure began the dramatic ramp up of China's university enrollment from the late 1990s.
