"If we did it before, we can do it now" is not anything close to a valid argument.
Also, "it's been done before" is a much better argument than "we think we can make these massive and untested changes to our society because my studies say so" like I see constantly from solar/wind maximalists on demand response, mass v2g, hyper connected grid, underground hydrogen battery etc, etc.
And even in China, renewables are outpacing new nuclear construction.
