This depends on how hooked one is to the "fat tastes good" mindset.
For me I love air frying and think all of Chicken, pork, fish etc tastes better in air fryer. i think french fries are better in an air fryer. But other people like KFC, other people like deep fried everything. It depends on the person. The benefits of an air fryer are obvious. For one you don't need a big vat of oil. you don't have the big risk of a potential oil fire. You have an appliance that is portable and you can use outside on hot days. you have the benefit of an appliance you can use unattended.
Proviso that most air fryer recipes use slight amount of oil, maybe tablespoon, just to coat. I do think the flavor of meats, veggies is better in an air fryer. You can also make cakes in them. Mine is also a slow cooker, pressure cooker, several options. Like others have mentioned it becomes an alternate way of making foods you already consume. People will use it to make anything from egg rolls to pizza to TV dinners to popcorn lol
