In evolutionary biology, there's this idea that "evolution is stingy" – in most cases, a species doesn't have substantially more capability than it needs to survive (human brains are an often cited exception). I kind of expect that, outside of a computer, most product design should be err on the side of being stingy too. If I buy a toaster, I don't need it to be wi-fi connected so it can send me a text notification when the toast is done. I say this satirically, but I genuinely wouldn't be surprised if one existed. Frackin' toasters.
