X2. The US (and other countries) NEED to have locally produced supply of the chips that are used in items that are must-haves in their economies. Such as the chips needed in every domestic automobile. Also only locally produced chips should be used in any kind of system (including internet and computers) that are involved in any kind of secure systems.
There's no doubt that China will become a major chip producer but the US and other countries must have an independent, security safe and reliable chip supply of their own, even if the chips themselves will cost more.
An electronic engineering company that I worked for many years ago (back in the 80's, and it no longer exists) sold a product to one of the Arab countries. After a while the customer needed an electronic board that was used in one of the systems. We sold them the board and they returned it because one of the power transistors had RCA printed on the top of it, (along with the transistors part number). And that country had a ban on anything from RCA being imported to it. When we got the board back, the shop used an ink pen eraser to rub away the RCA letters from the top of that power transistor, and recoated the board with clear Krylon paint, (you could see the scratches where the RCA letters had been removed, even after it was again sprayed, if you knew where to look), I then retested it, and it was shipped back to them.
Moral of the story, just because a chip or transistor is banned from being imported from a certain country, does not guarantee that some of those items will never get through such an embargo.
Another true story about shipping electronics to a customer in another country. One of the engineers had to take a trip to China to be there when some computers we sold them were used for the first time (they were to be use to control that huge dam, and we had had people from China over here for about a month for training). And also, at the same time a customer in an African country/nation needed an electronic board for a system they had previously bought from our company here in the US. They wanted that board in a big hurry (it was for a mining project and without that system working they were losing money big time for every hour that it was down), so it was decided that the traveling engineer would divert on his trip to deliver it in person. However, the paperwork required before such a board could be shipped to them would take weeks or even months to process. Our company called them up and told them of this problem, and they said to wrap the board in a bath towel along with a hundred-dollar bill and put that in the engineer's luggage, and to add a hundred dollars to the price of the board. That was done, and when the engineer arrived in that country the hundred-dollar bill was gone, and the board was still in the towel.
Moral of the story, --- same as above ---.
