alt Hacker NewsI don't think that works in the situation of fabs. They are big and expensive pieces of tech with the latest fabs being the most expensive to construct.
You can't exactly break up a chip manufacturer when they have just 1 or 2 plants tooled for the latest memory.
IMO, recognizing chip fabrication as a national security asset and turning it into a public corporation would be the better way to go. Let the likes of intel/amd/or micron continue developing chips. But also, take control of the most expensive and risky part of chip manufacturing to make sure we don't fall behind due to corporate budget cuts. You also keep and continue to build expertise in a vital part of modern society.
I mean, to take that one step further, if the underlying process-node technology (e.g. EUV) were nationalized, then you an entire nation-state's budget (and ability to get cheap loans) could be thrown at the problem of rapid horizontal buildout of fab capacity. Economics similar to nuclear power generation.
