I agree with criticism of not made anything… Yet.
Validation of advances will come with product availability, instead of press releases. We definitely need more computing related production with western supply chains all pivoting away from “normal computing”





Actual EUV production in west started at 7nm in 2019. Device/chip sales did not skyrocket. TSMC/ASML did 5x in value over the time and are the most successful benefiaries of EUV, but most of the gains are during this AI era.
If you mean effect on US stock market from Chinese EUV production, it did take 9 years between EUV availability/existance and commercial production. China has solid 7nm production already, though costs are higher than tsmc. 5nm chips are in successful Huawei products this year already. Huawei released a patent for DUV 2nm chips this month. Near term improvement in the above processes will have much higher near term impact. Non US colonies will buy Chinese phones/PCs, like EVs, as Huawei software (Harmony OS) is already best in class, and production of other phone/pc associated hardware is enough to make great products.
Industry/west needs more short term RAM production, and China is likely to be the fastest source of ramping up that production and selling to west. Traditional chip industry will collapse if extortion/shortages persist in 2026.
I predict steady share gains in chips from China, rather than “a singularity EUV” moment on stock market.
