Surely the pinnacle of design here would simply be two buttons: "I'm too hot" and "I'm too cold" (assuming you couldn't somehow automatically measure that state e.g. contactless thermometers).
All the complexity of deciding resulting target temperature and fan speed is work that an elegant and intelligent system should then perform for the end user. If it can't be determined automatically, try harder or add more controls.
As a counter, inflationary systems slowly transfer more and more wealth from those without assets, to those with.
It might be different if wages grew at the same rate as inflation, but they rarely do.
The standard target rate of 2% inflation does not take into account the deflationary effects of ever increasing technology / efficiency. So in reality, it's much higher then the 2% stated figures.
An example of where this approach is problematic: many ecommerce product pages feature embedded json that is used to dynamically update sections of the page.
