moore's law is just the observation that chips are 2d: linear shrinks produce exponential benefit. I can't see anything like a linear/square relation in fusion reactor design (even accepting that ML's premise of shrinks being linear in time is not a law, just something that sometimes happened, and sometimes didn't...)
