This is true on a micro, per-interaction scale. On a macro scale, it can be more beneficial in the long run for people's egos to be hurt when they're wrong. For someone like Torvalds, the macro scale of interaction matters a lot.

You're basically supporting the "everyone's a winner" mindset.

On the macro scale, it's better to feel the sting of being wrong so you can learn from it.
