They are new names for old tools.
Old French and hispanic grandmas have been crushing dinners in pressure cookers since the 17th century. I like the instant pot because I don’t have a ticking time bomb rocking back and forth on my burner. If you called it “electric pressure cooker” no one would buy it, call it an Instant Pot and get a few mommy bloggers posting on instagram and you are drinking vintage Krug on a yacht in Miami.
Air fryers are just convection toaster ovens with a different shape and name, and marketed to fat people to feel better about eating so many mozzarella sticks, pizza rolls, reheated dominos, and French fries.
“My crispy fries come out better than deep frying!” no shit, you know Ora Ida dips them in oil before freezing them right?
