What comes to your mind when you imagine something with corners? Tables, AirPod cases, chairs — notice what they have in common? All their corners are round. There’s no doubt that soft corners are objectively better than the cookie-cutter edges that practically cut triangles into your eyes.
There is only one valid exception: paper, which is a perfect rectangle. Who doesn’t revel at an immaculate sheet of unused, pristine paper?
But aside from that, sharp corners are the most jarring things. No one (though I can’t account for those who have eccentric tastes) has ever walked past a building and thought, “Darn, those corners are so sharp,” or “I wish those corners were sharper.”
Sharp corners are aesthetically unpleasant and a safety hazard. They’re the worst of both worlds; they’re neither beautiful nor functional, and I don’t understand why someone would prefer them anywhere at all.
