SV is good at Software, UI/UX and, historically anyway, Silicon.

But it can't do end hardware.

And the stuff it has been successful at is designing consumer hardware but outsourcing the manufacturing to another country.

Arduino is Italian. Samsung is South Korean. TSMC is Thai. ARM and RPi is British. Shenzhen is the hardware place to be now. It didn't even steal that crown from SV. It stole it from Akihabara.
