but my point is that the question "what kitchen gadget is completely useless" is the wrong question unless one provides a lot more context about their own situation including what their level of mobility is, how much space do they have in their kitchen, how many people are they cooking for and how much food do they want to cook at once, what kind of food do they want to cook, how they like to cook, what tasks they personally might enjoy or not enjoy, etc.

With all due respect, that is an insane amount of information to expect for a small question. Does everyone need to have a graduate level degree to participate in conversations?

It's extremely exhausting to have to be so high strung all the time.
