Coming from Europe, where air conditioning is not really a thing (outside of places of business), yes, you are probably right. It is not a need. But neither is clothing in most parts of the world, or houses larger than a bed, or food that's not oatmeal and the random scavenged fruit. Creature comforts matter. I've been to Morocco lately, with dry 45-48 degrees celsius outside. I've experienced that "vernacular architecture". Every single one of those buildings I have been in (including stalls in the soukh, which is ridiculous because they are essentially missing a wall towards the street) had some form of air conditioning retrofitted. Of course, the tendency of Americans to set their air conditioning to below 20 degrees is ridiculous.
