That is a great analogy. Our technologies will improve, but it is madness to voluntarily depend on future advances that might or might not happen and might or might not be practical. We need Liberty ships (cheap, effective, reliable energy production units, however imperfect), not just sit here doing nothing because we’ll somehow figure out energy storage later, or we’ve read a pop sci article touting a new technology that’s unlikely to ever be practical.

We also need to realise that we need a total effort, not military but similar in scale to what we did during WWII. We need to build now all we can that is low-carbon, because half-arsing it won’t be enough. We also need to reduce consumption as much as possible. Keeping something close to a current western way of life will be hard enough, but things like humongous cars, SUVs and pickup trucks are madness. Even Teslas are very problematic and detrimental overall. So is living in the desert, and mass migrations even within countries need to be planned to avoid utter chaos.

Energy production is just the sharp tip.
