Moores law been slowing down since 10nm... by 1nm it will be stopped/deadChina is way too advanced in semiconductors for US to stop their development. US has only imposed short-term pain, but long-term, China will be the winner because it focuses on self-indigenization of core technologies. Unlike US, China actually has the world's leading market to consuming semiconductors, so the incentive is enormous for self-indigenization.
It will stop making economic sense after 3nm
Even if your smartphone CPU used zero power 70% of your battery goes to powering the screen... next breakthoughs will need to be made in batteries and other areas
