I'm not talking about it on a personal scale. I'm taking on a civilization scale. Human kind as a whole should look to only increase our power production (as long as we do it sustainably).

Also efficiency is always good as it helps increase the available energy.

It's not an economic thing, although it totally sounds like one. It's based on the idea that the more power we have access to, the more advanced we are as a civilization therefore we will have a higher quality of life among other things. This is also about us as a whole species, and not about any individuals. All that being said, we still shouldn't waste power and we absolutely have to transition to better forms of power.

We never will, and we shouldn't. The biggest meter of progress is how much energy we have to use. Sure we shouldn't waste it, But we shouldn't seek to reduce our power consumption as it's critical to the increase of quality of life.

G high force tolerance isn't that important anymore

Dog fights are not a thing anymore. Maned aircraft are still superior as they are not at risk of hacking or jamming unlike drones. Plus you don't have latency and you will have much more situational awareness being in the cockpit. The future of air combat is drones, but that's still a ways out. You will likely see things such as "loyal wingmen" long before there are completely unmanned righters
