Sleepy34 is such a fool. By the same logic, China could hurt the American auto industry badly because the US uses so many Chinese auto parts like tires, windshields, etc. Same can be said for many other industries of the US, too.Can all be substituted with Chinese or Japanese products. Japan is basically an open supplier, even selling to the Soviets historically. Japanese example: Shimadzu
Chinese suppliers are basically held back solely by market momentum, just as you saw with the semiconductor sector, not any technical issues.
Simple example: United Imaging which makes full body MRI, one of the most complex scientific instruments in the world with complexity on par with jet engines and supercomputers. Now one of the largest MRI suppliers in the world.
Commercially available scientific instruments are also not on the cutting edge - those are custom built as one of a kind tools. They're for QC or process analytics. And for those, many non-technical features are considered ie service and price.
Keep this troll around is doing more harm than good to the forum.
