Meanwhile the Chinese are rapidly building out their fleet of nuclear reactors because they're an actually practical people.
This doesn't mean nuclear is a mistake per se, but if the central government decides nuclear is practical, and it turns out they are wrong, it's very probable they keep building them and then some well after they are costing more money than they produce. In the US the investors would go bankrupt, and the plant development abandoned.
Which confirms your statement, they are a practical people. They have despite much lower labor costs than in the western world and a dictatorial safety and decision making culture come to the conclusion that renewables will power the vast majority of the grid.
