Reforming English spelling would make it easier for people to learn English, but it could also theoretically have some negative effects as well. For example, it's possible that the bizarreness and irregularity of English spelling have a stimulating effect on the mind that has grasped them and lead to enhanced creativity in a similar way to how the minor variations between musical instruments of the same general type, or between paintbrushes, can lead to interesting creative results. Also, part of the aesthetic effect of written text comes from the exact sequence of characters.
