I would say it matters insofar as anyone wants to apply understanding of the fundamentals of cooking to new tools. Should I expect to use an 'air fryer' to do things I can already do with other tools—like toast bread or roast/bake something small, even though none of those is 'frying'? What are important considerations / differences relative to the small convection oven I already have? If air frying is a fundamentally new cooking technique, then I may not be able to apply a wealth of cooking knowledge & intuition when using it, other than basic food chemistry. If it's a rebranded convection oven, then I can decide if a different form factor is worth it for things I already know how to do. Does that make sense?
