I think I know the reason so many people have differing opinions on the sharpness. I don't feel the sharpness at all when I'm typing or searching the web for things and using the trackpad occasionally. But when I use the only the trackpad for hours (e.g. when playing Civilization VI while watching TV), then the edge slowly makes a harsher and harsher impression on my hands whether I'm wearing long sleeves or not. The edge is definitely not rounded and is unpleasant to rest one's hands upon. Most people, when typing, or using the keyboard mostly, rest their wrists on the edge at a fairly oblique angle. But when using the trackpad - and when using the laptop on a lap - it's the hands that are pushing against this squared-off edge. I would genuinely upgrade to a newer Macbook (I'm on the M1) if a later iteration didn't have this hard corner, just for games.
