Why are you comparing the most common screen resolution in 2007 to a 4k monitor today? 4k isn’t the most common today. This isn’t a fair comparison.

Vector mathematics as we use it and code it is based on the right hand rule.

Agreed. That would be totally valid.

The top one is wrong because it violates the right hand rule.

At least where I’m from (Canada), bread comes with a clip holding the bag shut, not a twist tie. “Re-using the clip” means the clip the came with the bag. You can see that it’s a different shape in the picture. This would be the equivalent of re-using the twist tie, if that’s how the bread is packaged where you live.
