If by this you mean that it hasn’t gotten cheaper over time, that’s only true in countries where there hasn’t been multiple waves of plants built over time to allow the construction crews to learn and then apply that knowledge. In Japan cost scaling did indeed happen more or less exactly as economics predicts.

This is, I assume, the point that gp is making. We’re about to learn whether the same cost reductions from repetition that happened in Japan will happen in Georgia.
