Well, by that logic, I have some great sophistication going on in my household.. Several devices that took EUV machines(that cost hundreds of millions each) to etch login onto themselves - microchips on my laptop, phone etc. A pipe constantly supplying flammable gas that was probably mined thousands of kilometers away just so that I can burn it and heat up my water for shower. A very dangerous to the environment - refrigerant in both my fridge and heat pump. A tank full of dinosaur juice in my car, which itself was machined and built with some exotic metals mined somewhere else in the world. What difference is a few more kilograms of futuristic substance that can save energy for my house make? I know hundreds or thousands of kilograms of LFP batteries in my backyard in feasible today. But who knows. Maybe we will find a way to mine Lithium or replace it with Sodium and the whole process would become “normal” like the metals in my 3 ton car.
