Well, indoor heating is clearly more and more becoming a luxury on the affordability side, enough so that putting a jacket inside is my first go to option when I'm alone at home as I work remotely. But not yet so excited expensive as to private my children from its been benefits when they come back home. And of course nothing like a jet, indeed.
Plumbing is generally not also considered a luxury over here. But at mankind level, I do feel particularly privileged on this regard. I remain amazed we have water flowing at will, and even possibility to take hot shower every day. This is not a jet level kind of privilege, but I try to keep myself aware of how incredibly lucky I am to be able to benefit of such a technology and infrastructure.
I doubt humans waited AC to come alive for settling hot and humid areas. There are other ways to have cooled down residences which don't require so much sophistication in physic models before you can even dream to build a prototype.
All that said, I got your hint to document more on how/why AC is so much more used in some area, and I'm just starting my journey on learning about it.
I still doubt that local climate alone explain the difference in term of how common it is in different region of the world. For example USA have a very large set of different local climate, but from what I understand most homes have AC.
