Sugar (or condensed milk) in tea I get often stays unmixed at the bottom. I forget to stir it.
Is that poor design that should be fixed?
Or is the steadily increasing sweetness of the tea a brilliant feature?
Anyway, I therefore lick the bottom of the cup to get every last bit of sweetness.
But this cup is so deep that my tongue can just about reach the bottom.
And I can’t reach the botom near the handle, because my nose is in the way.

Is that poor design that should be fixed?
Or is the 3 minutes of delight I get from fighting with the cup, making it a game, a brilliant feature?
Now that I’ve had it, I probably shouldn’t take sweets until the evening.
Is that agony poor design that should be fixed?
Or is the delight of one chunk of chocolate after a day of abstinence and yearning a brilliant feature?

(My brain feels there’s some cool insight here, but can’t figure it out. Is that poor design? Or our best differentiator from AI?)
