Sorry, was an offhand remark about solutions that may end up harming us further when applied on a planet-wide scale. How much of this stuff needs to be made to actually have an effect, and with how much energy? When any attempt at reducing CO2 is met with city-sized warehouses full of kW GPUs powered by gas turbines, adding to century’s worth of GHGs you start to feel what is the point of even trying to pretend there’s a way out.
