I think a current trend is for people to make do with less central AC use than before. We have three zones in the house - one for the downstairs, one for the master bedroom, and one for all the upstairs.
I have been leaving the main downstairs at 88 during the day, the master bedroom at 78 (only at night on the timer-thermostat), and using fans. The upstairs is left off all the time.
This is in Dallas (it gets HOT here) and has literally cut my highest August electric bill from around $500 before (when the kids were living at home and we ran everything in the low 70s) down to around $200 or less.
For sure, when I was a young kid in the 1950s, we managed without any AC for years and then later with only an evaporative cooler.
