Old ways of spelling need to be revised since English is a very hard language to master. For instance, "tough" can become "tuf" and the like. Making English easier to spell is one way to further the language and make it more accessible to everyone. The orthography needs to be revised to update the hundreds-year-old proscription for ways of spelling.
No, the English orthography should not be revised, because English has been working just fine for centuries. English is one of the most complicated languages that is true. But there are also puns and idioms that make the language fun. Scholars can continue to study the language, and it is effective for communication.
