    What’s stopping an American RAM plant? I would think we would have already broke ground.

      Americans do crazy things like not tolerating 24 hour shifts and being required to sleep in a dormitory owned by the employer.

      There’s been a lot of efforts to expand American fabs. Intel, Micron, and TSMC are all working on it (and I’m pretty sure most of those projects have at least broken ground at this point). But even with infinity dollars to spend, it takes a very long time to build these plants. The fabs are similar in size to a “normal” factory, but the entire interior is a series of massive clean rooms that are hundreds if not thousands of times cleaner than an operating room, filled with equipment that is simultaneously very large and very sensitive.

      I remember reading somewhere that one of Intel’s newest process nodes involves drilling holes measured in hundreds of picometers into the part at some point. A hydrogen atom is roughly 62 picometers across.
