> It's a tautological argument
It is not at all what I meant.
What I meant is that there is a need to go past that, and it is not clear that we are capable of doing it. It's great to say "wooooow, photovoltaic increased 1000% last year, McKinsey estimates (with the dumb uninformed extrapolations they love to do) that in 10 years it will have replaced all energy", but if you are serious, you should acknowledge that it is still the easy part.
I am not saying "it is not possible", just "think about it: it may be harder than expected".
