OK so here we go. A squig asked what Jack thought of airfryers. Her reply: she received two as gifts and gave one to her parents and one to a food bank. Her reason? She is "funny" about "specialist equipment from an 'accessible to the majority/recipe testing' point of view." Which tells us that she really is out of touch--never was in touch?--with anything.
Airfryers are not specialty equipment. They are pretty damn ubiquitous, inexpensive to buy and run. For a person worried about heating/electric costs, they are far cheaper to run than a stove/oven. They can be used in any housing with a socket. You can find them used quite easily (and cheaply). The only people in my circle who consider these specialty appliances are wealthier folks who own a stove/oven, microwave, toaster oven, sandwich press, Fry Baby, etc. So, middle class folks who have no need to delve into the airfryer's versatility as a cooker.
ETA: She was the one who treats a blender as a necessary, disposable appliance.
