The steelman of the argument is that, due to legacy in technology and comparative advantage, unless they expect a serious supply chain tech, many core technologies will be too expensive to duplicate for China and so there will be areas where they will not advance. There is some amount of evidence that was true for lithography, they did not seem to be making much progress until they were forced to, and there didn't seem to be enough capital available in China to catch up.

Of course, the extent to which they was true and for how long it would be true is up for debate, but it's not a prima facie foregone conclusion

I'm not an expert at all so I have to wonder which core technologies were/are too expensive to duplicate for China? Afaik semiconductors represent the cutting edge of manufacturing technology; if China is able to duplicate (or even innovate, as demonstrated by "3d Logic folding") in this industry, I can't imagine how any other sectors would be too expensive to duplicate.

Who knows how far they progressed in lithography once it became clear that withholding technology would be the official state policy-- I heard the Chinese state got involved in developing EUV in a way comparable to the Manhattan project in scale and secrecy.

		The cost is not just pure development. There are very high switching costs, and downstream opportunity costs affecting the entire ecosystem. As an example, Nikon was competitive with ASML in DUV for a while, but no one was willing to switch because the cost/risk was way too high. For lithography, that was essentially the issue - no serious foundry was willing to take the massive risk to move away from ASML - and, worse, to skip EUV. A second reason is that Chinese foundries still had to compete with foreign foundries. The cost of doing lithography with new Chinese DUV machines will be significantly higher than with ASML DUV and then significantly higher than with ASML EUV. So to build an ecosystem that can one day truly compete with ASML, you'd need the entire Chinese semi industry to take significant losses to get to the point where they can compete with ASML and pose a threat in the market. There is still many sectors like this where China has some kind of parity, but at a total cost of ownership so much higher than western competitors than they are not a serious market threat in the near future. In fact, the US, EU, etc... are in similar positions. Unless the Chinese economy becomes much stronger than the US/EU across the board, one would expect it to be case due to comparative advantage - the cost of directing industry to ignore superior alternatives will slow them down in other fields, unless the Chinese economy is just that much more effective.

They have the entire resources of their state available for funding.

They will catch up and pass the West.

Take nuclear weapons: even Pakistan and North Korea were able to catch up.

		Poor examples. Pakistan with a lot of Saudi backing, NK with a lot of Chinese backing. That aside, China will master chip making at bleeding edge global scale, just as it did with EVs and rare earth processing, etc.
