Re: "good enough" is all they'll ever need.
Exactly. Apart from the 'more money than sense' brigade (who, these days buy Hasselblad badged Point & shoot cameras), the majority of people taking photos have never wanted nor needed. What were the most popular cameras of the last century? I can guarantee it wasn't the Canon 1DX!
Box Brownies, 35mm (and then digita) compacts, bloody Instamatics, 110 cameras - these were the cameras most non togs used. Quality was acceptable to the majority of the users.
Phone cameras fill that gap - cheap, not terribly capable, certainly not professional quality, but they are definitely as good, convenient and fit for purpose as any of their predecessors
