I remember reading around the 300nm transition that Moore’s law was all over because wavelengths and physics. No one was talking about multiple masking patterns, probably because it was prohibitively expensive. Inconceivable, much like trillion dollar companies in the early 2000s.

I remember a quote from Von Braun where he learned to use the word 'impossible' with the greatest caution.

When you have a significant fraction of the GDP of a super power dedicated to achieving some crazy engineering task, it almost certainly can be done. And I wouldn’t bet against our hanger for better chips.
