I've seen idiots before but believe me , none more than the Wumaos & among wumaos none a bigger idiot than you . You talk about China being in a position to fabricate 7nm & 5 nm SMCs & you then post a picture with the headlines - China close to shipping 5 nm chips despite western curbs & right below the headlines the line - SMIC is facing lower yields as it makes 5 nm chips for Huawei smartphones.
So I state you may well come out with a 5 nm SMC but its yields will be the lowest in the business by which time TSMC & Samsung are now coming out with the 3 nm SMC .
We're in the process of setting up fabs for 28 nm SMCs which will start mfg in a couple of years. Do keep up with the times . From there to 7 nm SMCs should take us a decade . Hence around 2035-27 , we should be where you are today. Where would you be by then ? Either in Taiwan OR ...........
To be honest except for China , SMC fabs can be set up anywhere in the world as they are being set up . China's capacities are going to be a thing of the past. Where exactly do you propose to sell those Huawei smartphones when the US has barred Alphabet / Google from providing Huawei with authorisation to the Android OS ?
Without this Android OS who exactly is going to buy Huawei except in Zhongguo or a few other SE Asian & African countries that too in low numbers . Gradually you'd see other Chinese cell phone OEMs like Xiaomi , Vivo , Oppo , etc in the same category of exclusions like Huawei.
This will then be extended to your EV junk. Hence you may well possess mfg capacities in unlimited numbers but where are you going to sell your merchandise to ? Lots of good & exciting news & developments like these are coming your way.
