All this fuss about china spying, putting backdoors in telecoms tech, and restrictions to prevent acces to hardware... And Cisco announced today a 0 day exploit on 10s of thousands of its systems being actively exploited in the wild... And it's not the first. I guess the same scrutiny doesn't apply to domestic tech.
These restrictions do nothing but damage the global free market economy and push the Chinese to become even more self-dependant. Anyone with half a brain knows the current restrictions have done next to nothing to stem advanced chip development in China, if the new hisilicon chip is anything to go by, but rather have forced china to invest in its own industries, hence why SMIC can now manufacture 7nm chips. The advanced stuff being restricted obviously has the potential for nefarious applications, but it's billed as a national security measure to slow Chinese military hardware development... You don't need a cutting edge RTX4090 to power a generation 5 jet fighter... You need a reliable and tested MCU probably based on a z80 or using risc V. This cutting edge military hardware was designed 15-20 years ago with that tech.
I fear that continued restrictions will fragment the global computing market, and not to the benefit of the US, if it does indeed decide to restrict access to RISC-V the rest of the world won't follow suit, so it's a self destructive policy. Why do business in the US if you can't do global business with other major economies. China is going to develop domestic tech on par with US domestic tech within the next few years, but without US oversight or control over hardware they used to make that china bought.
