I never said US was good. I asked why China announced there are break thru in 7nm April last year and then no release of 7nm chips.Lol...do u know what you show are just study and technique which none are commercialize. If US is so good. Apple and Qualcomm wouldn't be begging Samsung and TSMC to made 3nm and 5nm chips for them.
Don't try misled the readers with your misleading statements. We all know the standard of US chip fabrication
You are the one that come out and tell me to shut up when US can't make 7nm, which they can and did. I never said anything about US being good at making chips, probably post 2024 will be when US start hosting TMSC fab plant in Arizona.

IBM unveils 2-nanometer chip technology for faster computing
For decades, each generation of computer chips got faster and more power-efficient because their most basic building blocks, called transistors, got smaller.
