Solar panels and batteries getting cheaper already happened. It's not hypothetical. It's a pretty small leap to say that it would have gotten cheaper earlier if we started earlier.
We're saying "what if power curve was evaluated at f(x + N) instead of f(X), where N is govt expenditure."
I'm listening, but not learning, and am just left with questions, because it begs questions.
N wasn't and isn't 0, so there's innumerable questions about N and it's magnitude relative to X, and Fs change.
"This is myopic solar propaganda, Wrights Law means we should have put every dollar into fusion" is similarly, true, but not illuminating, perhaps even shading.
