We have all the technological tools available to largely decarbonize energy. We don’t have to wait for, nor have the time, to wait around for a deus-ex-machina.

Given the dominance of state level actors in fossil fuel extraction (a role they did not have in horse based transport), to deny states have a role in decarbonizing energy seems naive. I don’t see what’s unreasonable to suggest that the current massive resources states put into supporting fossil fuel consumption and spending on wars to protect its production and distribution be redirected towards accelerating the adoption of modern clean energy production and use.

Well, considering that the issue was created by the same "human ingenuity" aka turbo-capitalism, I'm not sure that the solution could be found there. I mean, we had one of such capitalists that looked like he was 100% into "fixing it" and now probably thinks it's just a woke invention. You cannot rely on single people changing the future, because they can change their mind far too easily.
