@dalias @Daojoan It’s not a “cost” thing. It’s an actual resource scarcity thing. Including, by the way, energy. Storage is rare earth metals, minerals, and energy.
You’re right, “this won’t go on forever”. It didn’t; we’re now burning up 1.7 of earth’s yearly resources every year. This year, Earth Overshoot Day? August, 1.
And no, it’s not just “storage”. It’s unbridled growth (the idea of—) anyywhere. And that’s why #degrowth is a necessity. Everywhere.
