I demonstrated here just 1 example of how much different chips reside in 1 important component of an EV (which is electric power steering system)
And over time, I think the shift is already under way for China Inc to use domestic supply chain for these critical components.
Domestic suppliers will also use domestic chip production over time
All about de-risking
Building mature chip fabs alone do not mean anything. They need to find customers. Customers are available due to de-risking reasons.
