In 1945 as World War 2 wrapped up and the Cold War started, many in the US believed that it would take the Soviet Union 20+ years to build the atomic bomb. It took 4 years. There were several reasons for this. It became a national security interest, there were leaks to the USSR by people who thought the US shouldn't have a monopoly on the bomb and Americans in general viewed the Soviets as backward farmers.
I see the same thing with China. It's not so much espionage now (although there might be that) but China instead will just hire people with the right knowledge, so former employees of ASML, Nvidia, TSMC, etc.
I've been saying for awhile that China won't tolerate the export ban on ASML's best lithography machines and NVidia's best chips. It's a national security issue. And China is the one country on Earth I have faith can dedicate itself to a long term goal.
And yet I got the same reaction. "The Chinese will never catch up", etc. Reports have been comiung out that Huawei has started developing and using their own 7nm chips.
Weirdly, the US created this problem. By restricting exports of chips to China, Chinese manufacturers had no choice but to develop their own chips. Had China been flooded with NVidia chips, there would be far less market opportunity.
The American economy is essentially a bet on an AI future now. Were it not for like 7 tech companies, we'd be in a technical recession. I also believe that bubble is going to burst. But the economy as a whole pretty much now requires US dominance of an AI future and I think a lot of people are in for a rude shock as China completely disrupts that.
China hasn't caught up yet. There are still many steps in the supply chain and chip design as a whole but making their own chips at sub-7nm is a massive step in that direction.
